Bitcoin Mining Pool – (Cryptocurrency Miner – Bitcoin Miner)

"My transaction is stuck, what to do?" - an explainer [DRAFT]

In the last days we have been experiencing a sharp rise in price, which is historically correlated with many people transacting over the Bitcoin network. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future. Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. Although the network is working as intended (blockspace is a scarce good, subject to supply/demand dynamics, regulated purely by fees), people who are unfamiliar with it might feel worried that their transaction is “stuck” or otherwise somehow lost or “in limbo”. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.

TL;DR: Your funds are safe. Just be patient* and it'll be confirmed at some point. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins.

You can see how the mempool "ebbs and flows", and lower fee tx's get confirmed in the "ebb" times (weekends, nights): https://jochen-hoenicke.de/queue/#0,30d
* if you are in hurry there are things like RBF (Replace By Fee) and CPFC (Child Pays For Parent), which you can use to boost your transaction fees; you will need an advanced wallet like Bitcoin Core or Electrum for that though. Keep also in mind that this is not possible with any transaction (RBF requires opt in before sending, f.ex). If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1, 2.
Here’s how Andreas Antonopoulos describes it:
In bitcoin there is no "in transit". Transactions are atomic meaning they either happen all at once or don't happen at all. There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. Either the transaction happened or it didn't. The only time you can't see the funds is if your wallet is hiding them because it is tracking a pending transaction and doesn't want you to try and spend funds that are already being spent in another transaction. It doesn't mean the money is in limbo, it's just your wallet waiting to see the outcome. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.
tl;dr: your funds are safe

How is the speed of confirmations determined in bitcoin?

Open this site: https://jochen-hoenicke.de/queue/#0,2w
Here you see how many transactions are currently (and were historically) waiting to be confirmed, i.e how many transactions are currently competing with your transaction for blockspace (=confirmation).
You can see two important things: the differently coloured layers, each layer representing a different fee (higher layer = higher fees). You can point at a layer and see which fees (expressed in sat/byte) are represented in this layer. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is (miners work through the mempool always from the top, simply because the tx's on top pay them more). You can estimate that each newly mined block removes roughly 1.xMB from the top (see the third graph which shows the mempool size in MB). On average, a new block is produced every ten minutes. But keep in mind that over time more transactions come into the mempool, so there can be periods where transactions are coming faster than transactions being “processed” by miners.
The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point.
In short: what determines the speed of a confirmation is A) how high you set the fees (in sat/byte), B) how many other transactions with same or higher fees are currently competing with yours and C) how many transactions with higher paid fees will be broadcast after yours.
A) you can influence directly, B) you can observe in real time, but C) is difficult to predict. So it's always a little tricky to tell when the first confirmation happens if you set your fees low. But it's quite certain that at some point even the cheap transactions will come through.

So what happens if my transaction stays unconfirmed for days or even weeks?

Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. That’s why there is not a fixed amount of time after which a transaction is dropped from the mempool, but most nodes drop unconfirmed tx’s after two weeks [IS THIS CORRECT?]. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened. Keep in mind that in those two weeks the coins never actually leave your wallet. It’s just that your wallet doesn’t show them as “available”, but you still have options like RBF and CPFP to get your transaction confirmed with higher fees, or to “cancel” your transaction by spending the same coins onto another address with a higher fee.

Helpful tools to estimate fees for future transactions:

Here are some resources that can help you estimate fees when sending a bitcoin transaction, so you don't end up overpaying (or underpaying) unnecessarily. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here or here.
The order here is roughly from advanced to easy.
1) https://jochen-hoenicke.de/queue/#0,24h
Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past. Each coloured layer represents a different fee amount. F.ex the deep blue (lowest layer) are the 1sat/byte transactions, slightly brighter level above are the 2sat/byte transactions and so on.
The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. This should help you estimating how high you need to set the fee (in sat/byte) in order to have it confirmed "soon". But this also should help you to see that even the 1sat/byte transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool are always temporary. For that you can switch to higher timeframes in the upper right corner, f.ex here is a 30 days view: https://jochen-hoenicke.de/queue/#0,30d. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry.
2) https://mempool.space
This is also an overview of the current mempool status, although less visual than the previous one. It shows you some important stats, like the mempool size, some basic stats of the recent blocks (tx fees, size etc). Most importantly, it makes a projection of how large you need to set your fees in sat/byte if you want your transaction to be included in the next block, or within the next two/three/four blocks. You can see this projection in the left upper corner (the blocks coloured in brown).
3) https://whatthefee.io
This is a simple estimation tool. It shows you the likelihood (in %) of a particular fee size (in sat/byte) to be confirmed within a particular timeframe (measured in hours). It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that.
4) https://twitter.com/CoreFeeHelper
This is a very simple bot that tweets out fees projections every hour or so. It tells you how you need to set the fees in order to be confirmed within 1hou6hours/12hours/1day/3days/1week. Very simple to use.
Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

Bitcoin Mining Power Sees Short-Term Drop as Rainy Season Ends in China

Bitcoin Mining Power Sees Short-Term Drop as Rainy Season Ends in China
https://preview.redd.it/84jk6ssun2w31.png?width=1024&format=png&auto=webp&s=e11e42aea4b0346f9e2548bc0b0191dd0a966c90
After sustained growth over the past three months, computing power on the bitcoin network has seen a fallback as the summer rainy season trails off in China.
According to data from Poolin, the world’s largest bitcoin mining pool by real time hash rate, bitcoin’s seven-day average computing (or hashing) power has dropped to around 90 exahashes per second (EH/s) since Oct. 24, signaling that some miners have been unplugging from the network. It had previously been estimated that the hash rate would go above the 100 EH/s threshold by the end of 2019
As a result of the power drop, data from mining pool service BTC.com estimates that bitcoin’s difficulty – a measure of how hard it is to compete for mining rewards on the world’s top cryptocurrency by market value – will decrease by 1.5 percent when it’s set to adjust in about seven days.
Bitcoin’s mining difficulty had reached an all-time-high at 13.69 trillion on Oct. 24, following a 38 percent increase since early August. The climb resulted mainly from an increase in miners’ hashing power made possible by the abundant and cheap hydroelectricity in China’s southwestern provinces.
Mining difficulty is designed to adjust itself to go up or down about every 14 days, based on whether the hashing power on the network in the two-week cycle increases or declines, respectively. The Oct. 24 difficulty record followed a jump in the 14-day average hash rate to an all-time-high at 97.90 EH/s.
Poolin’s co-founder Chris Zhu said in a recent WeChat post that one main reason for the fallback over the last week is the gradual end of this year’s rainy season in China. As a result, some hydropower stations in China’s Sichuan province – estimated to account for 50 percent of bitcoin’s global computing power – no longer have the capacity to generate enough energy to support mining activities.
Miners without sufficient hydropower supply would have to shut down their operations or relocate to other provinces like Xinjiang or Inner Mongolio, where mining farms have a more stable, but more expensive, power supply generated from fossil fuel plants.
Xun Zheng, CEO of Hashage, which owns mining facilities in China’s southwestern Sichuan province, echoed Zhu’s comments, adding that even if some may still be able to find a hydropower resource, the cost has gone up from $0.04 per kilowatt-hour (kWh) in the summer to around $0.05.
Further, bitcoin’s sudden price drop on Oct. 23 to below $7,500 could have resulted in a large scale of shutdown of older but widely used mining models like the AntMiner S9 made by Bitmain. The S9’s profit break-even price point is between $7,000 to $7,500. However, the price’s significant rebound since last weekend may have stopped that panic.
The fact remains, though, that the profitability of the S9 and other similar modes made by Bitmain’s rival miner makers, is a critical issue for their utility lifespan. And that may soon be affected by the higher winter cost of electricity in China, as well as the scheduled halving of bitcoin mining rewards in May 2020 – before next year’s rainy season.
According to a miner profitability index provided by Poolin and its rival F2pool, at bitcoin’s current price and an electricity cost of $0.05 kWh, the mining profit margin of models like S9 is about 30 percent.
Some, like INBTC, a sister company of Poolin, are currently making efforts to extend the life of the S9 miner by merging two units into one in an attempt to generate a higher ratio of hashing power over electricity consumption. That would allow a higher daily profit margin than would be achieved using two individual units, though it remains to be seen if such a method can be proven to work and adopted on a large scale.

Bitcoin Mining Profitability: How Long Does it Take to Mine One Bitcoin in 2019?

When it comes to Bitcoin (BTC) mining, the major questions on people’s minds are “how profitable is Bitcoin mining” and “how long would it take to mine one Bitcoin?” To answer these questions, we need to take an in-depth look at the current state of the Bitcoin mining industry — and how it has changed — over the last several years.
Bitcoin mining is, essentially, the process of participating in Bitcoin’s underlying security mechanism — known as proof-of-work — to help secure the Bitcoin blockchain. In return, participants receive compensation in bitcoins (BTC).
When you participate in Bitcoin mining, you are essentially searching for blocks by crunching complex cryptographic challenges using your mining hardware. Once a block is discovered, new transactions are recorded and verified within the block and the block discoverer receives the block rewards — currently set at 12.5 BTC — as well as the transactions fees for the transactions included within the block.
Once the maximum supply of 21 million Bitcoins has been mined, no further Bitcoins will ever come into existence. This property makes Bitcoin deflationary, something which many argue will inevitably increase the value of each Bitcoin unit as it becomes more scarce due to increased global adoption.
The limited supply of Bitcoin is also one of the reasons why Bitcoin mining has become so popular. In previous years, Bitcoin mining proved to be a lucrative investment option — netting miners with several fold returns on their investment with relatively little effort.
bitcoin mining hardware
Mining Hardware
The mining hardware you choose will mostly depend on your circumstances — in terms of budget, location and electricity costs. Since the amount of hashing power you can dedicate to the mining process is directly correlated with how much Bitcoin you will mine per day, it is wise to ensure your hardware is still competitive in 2019.
Bitcoin uses SHA256 as its mining algorithm. Because of this, only hardware compatible with this algorithm can be used to mine Bitcoin. Although it is technically possible to mine Bitcoin on your current computer hardware — using your CPU or GPU — this will almost certainly not generate a positive return on your investment and you may end up damaging your device.
The most cost-effective way to mine Bitcoin in 2019 is using application-specific integrated circuit (ASIC) mining hardware. These are specially-designed machines that offer much higher performance per watt than typical computers and have been an absolutely essential purchase for anybody looking to get into Bitcoin mining since the first Avalon ASICs were shipped in 2013.
When it comes to selecting Bitcoin mining hardware, there are several main parameters to consider — though the importance of each of these may vary based on personal circumstances and budget.
Performance per Watt
When it comes to Bitcoin mining, performance per watt is a measure of how many gigahashes per watt a machine is capable of and is, hence, a simple measure of its efficiency. Since electricity costs are likely to be one of the largest expenses when mining Bitcoin, it is usually a good idea to ensure that you are getting good performance per watt out of your hardware.
Ideally, your mining hardware would be highly efficient, allowing it to mine Bitcoin with lower energy requirements — though this will need to be balanced with acquisition costs, as often the most efficient hardware is also the most expensive. This means it may take longer to see a return on investment.
In countries with cheap electricity, performance per watt is often less of a concern than acquisition costs and price-performance ratio. In most countries, operating outdated mining hardware is typically cost prohibitive, as energy costs outweigh the income generated by the mining equipment.
However, this may not be the case for those operating in countries with extremely cheap electricity — such as Kuwait and Venezuela — as even older equipment can still be profitable. Similarly, miners with a free energy surplus, such as from wind or solar electric generators, can benefit from the minimal gains offered by still running outdated hardware.
Longevity
The lifetime of mining hardware also plays a critical role in determining how profitable your mining venture will be. It’s always a good idea to do whatever possible to ensure it runs as smoothly as possible.
Since mining equipment tends to run at a full (or almost full) load for extended periods, they also tend to break down and fail more frequently than most electronics — which can seriously damage your profitability. Equipment failure is even more common when purchasing second-hand equipment. Since warranty claims are often challenging, it can often take a long time to receive a warranty replacement.
Price-Performance Ratio
In many cases, one of the major criteria used to select mining hardware is the price-performance ratio — a measure of how much performance a machine outputs per unit price. In the case of cryptocurrency mining hardware, this is commonly expressed as gigahashes per dollar or GH/$.
Under ideal circumstances, the mining hardware would have a high price-performance ratio, ensuring you get a lot of bang for your buck. However, this must also be considered in combination with the acquisition costs and the expected lifetime of the machine — since the absolute most powerful machines are not always the cheapest or the most energy efficient.
Acquisition Costs
Acquisition costs are almost always the biggest barrier to entry for most Bitcoin miners since most top-end mining hardware costs several thousand dollars. This problem is further compounded by the fact that many hardware manufacturers offer discounts for bulk purchases, allowing those with deeper pockets to achieve a better price-performance ratio.
Acquisition costs include all the costs involved in purchasing any mining equipment, including hardware costs, shipping costs, import duties, and any further costs. For example, many ASIC miners do not include a power supply — which can be another considerable expense, since the 1,000W+ power supplies usually required tend to cost several hundred dollars alone.
Ensuring your equipment runs smoothly can also add in additional costs, such as cooling and maintenance expenses. In addition, some miners may want to invest in uninterruptible power supplies to ensure their hardware keeps running — even if the power fails temporarily.
asic mining
Current Generation Hardware
One of the most recent additions to the Bitcoin mining hardware market is the Ebang Ebit E11++, which was released in October 2018. Using a 10nm fabrication process for its processors, the Ebit E11++ is able to achieve one of the highest hash rates on the market at 44TH/s.
In terms of efficiency, the Ebang Ebit E11++ is arguably the best on the market, offering 44TH/s of hash rate while drawing just 1,980W of power, offering 22.2GH/W performance. However, as of writing, the Ebang Ebit E11++ is out of stock until March 31, 2019 — while its price of $2,024 (excluding shipping) may make it prohibitively expensive for those first getting involved with Bitcoin mining.
Another popular choice is the ASICminer 8 Nano, a machine released in October 2018 that offers 44TH/s for $3,900 excluding shipping. The ASICminer 8 Nano draws 2,100W of power, giving it an efficiency of almost 21GH/W — slightly lower than the Ebit E11++ while costing almost double the price. However, unlike the E11++, the 8 Nano is actually in stock and available to purchase.
ASICminer also offers the 8 Nano Pro, a machine launched in mid-2018 that offers 80 TH/s of hash rate for $9,500 (excluding shipping). However, unlike the Ebit E11++ and 8 Nano, the minimum order quantity for the 8 Nano Pro is curiously set at five, meaning you will need to lay out a minimum of $47,500 in order to actually get your hands on one (or five).
While the 8 Nano Pro doesn’t offer the same performance per watt as the Ebit E11+ or AICMiner 8 Nano, it is one of the quieter miners on this list, making it more suitable for a home or office environment. That being said, the ASICminer 8 Nano Pro is easily the most expensive miner per TH on this list — costing a whopping $118.75/TH, compared to the $46/TH offered by the E11++ and $88.64 offered by the 8 Nano.
The latest hardware on this list is the Innosilicon T3 43T, which is currently available for pre-order at $2,279, and estimated to ship in March 2019. Offering 43TH/s of performance at 2,100W, the T3 43T comes in at an efficiency of 20.4GH/W, which is around 10 percent less energy efficient than the Ebit E11++.
The T3 43T also has a minimum order quantity of three units, making the minimum acquisition cost $6837 + shipping for preorders. All in all, the T3 43T is more costly and less efficient than the E11++ but may arrive slightly earlier since Ebang will not ship the E11++ units until at least end March 29, 2019.
Finally, this list would not be complete without including Bitmain’s latest offering, the Antminer S15-28TH/s, which — as its name suggests — offers 28TH/s of hash power while drawing just under 1600W at the wall. The Antminer S15 is one of the only SHA256 miners to use 7nm processors, making it somewhat smaller than some of the other devices on this list.
Like most pieces of top-end Bitcoin mining hardware, the Antminer S15 27TH/s model is currently sold out, with current orders not shipping until mid-February 2019. However, the S15 is offered at a significantly lower price than many of its competitors at just $1020 (excluding shipping), with no minimum quantity restriction. At these rates, the Antminer comes in at just $37.78/TH — though its energy efficiency is a much less impressive 17.5GH/W.

How To Select a Good Mining Pool
Mining pools are platforms that allow miners to pool their resources together to achieve a higher collective hash rate — which, in turn, allows the collective to mine more blocks than they would be able to achieve alone.
Typically, these mining pools will distribute block rewards to contributing miners based on the proportion of the hash rate they supply. If a pool contributing a total of 20 TH/s of hash rate successfully mines the next block, a user responsible for 10 percent of this hash rate will receive 10 percent of the 12.5 BTC reward.
Pools essentially allow smaller miners to compete with large private mining organizations by ensuring that the collective hash rate is high enough to successfully mine blocks on regular basis. Without operating through a mining pool, many miners would be unlikely to discover any blocks at all — due to only contributing a tiny fraction of the overall Bitcoin hash rate.
While it is quite possible to be successful mining without a pool, this typically requires an extremely large mining operation and is usually not recommended — unless you have enough hash rate to mine blocks on a regular basis.
Although it is technically possible to discover blocks mining solo and keep the entire 12.5 BTC reward for yourself, the odds of this actually occurring are practically zero — making pool collaboration practically the only way to compete in 2019 and beyond.
Selecting the best pool for you can be a challenging job since the vast majority of pools are quite similar and offer similar features and comparable fees. Because of this, we have broken down the qualities you should be looking for in a new pool into four categories; reputation, hash rate, pool fees, and usability/features:
Reputation
The reputation of a pool is one of the most important factors in selecting the pool that is best for you. Well-reputed pools will tend to be much larger than newer or less well-established pools since few pools with a poor reputation can stand the test of time.
Well-reputed pools also tend to be more transparent about their operation, many of which provide tools to ensure that each user is getting the correct reward based on the hash rate contributed. By using only pools with a great reputation, you also ensure your hash rate is not being used for nefarious purposes — such as powering a 51 percent attack.
When comparing a list of pools that appear suitable for you, it is a wise move to read their user reviews before making your choice — ensuring you don’t end up mining at a pool that steals your hard-fought earnings.
Hash Rate
When it comes to mining Bitcoin, the probability of discovering the next block is directly related to the amount of hashing power you contribute to the network. Because of this, one of the major features you should be considering when selecting your pool is its total hash rate — which is often closely related to the proportion of new blocks mined by the pool
Since the total hash rate of a pool is directly related to how quickly it discovers new blocks, this means the largest pools tend to discover a relative majority of blocks — leading to more regular rewards. However, the very largest pools also tend the have higher fees but often make up for this with sheer success and additional features.
Sometimes, some of the largest pools have a minimum hash rate requirement ù leaving some of the smaller miners left out of the loop. Although smaller pools typically have more relaxed requirements with reduced performance thresholds, these pools may be only slightly more profitable than mining solo.
Pool Fees
When choosing a suitable pool, typically one of the major considerations is its fees. Typically, most pools will charge a small fee that is deducted from your earnings and is usually around 1-2 percent — but sometimes slightly lower or higher.
There are also pools that offer 0 percent fees. However, these are often much smaller than the major pools and tend to make their money in a different way — such as through monthly subscriptions or donations.
Ideally, you will choose the pool that offers the best balance of fees to other features. Usually, the pool with the absolute lowest fees is not the best choice. Additionally, pools with the lowest fees often have the highest withdrawal minimums — making pool hopping uneconomical for most.
Usability and Features
When first starting out with Bitcoin mining, learning how to set up a pool and navigating through the settings can be a challenge. Because of this, several pools target their services to newer users by offering a simple to navigate user interface and providing detailed learning resources and prompt customer support.
However, for more experienced miners, simple pools don’t tend to offer a variety of features needed to maximize profitability. For example, although many mining pools focus their entire hash rate towards mining a single cryptocurrency, some are large enough to offer additional options — allowing users to mine other SHA256 coins such as Bitcoin Cash (BCH) or Fantom if they choose.
These pools are technically more challenging to use and mostly designed for those familiar with mining, happy to hop from coin to coin mining whichever is most profitable at the time. There are even some exchanges that automatically direct their combined hash rate at the most profitable cryptocurrency — taking the guesswork out of the equation.

Best Mining Pools for 2019
The Bitcoin mining pool industry has a large number of players, but the vast majority of the Bitcoin hash rate is concentrated within just a few pools. Currently, there are dozens of suitable pools to choose from — but we have selected just a few of the best to help get you started on your journey.
Slushpool was the first Bitcoin mining pool released, being launched way back in 2010 under the name “Bitcoin Pooled Mining Server.” Since then, Slushpool has grown into one of the most popular pools around — currently accounting for just under 10 percent of the total Bitcoin hash rate.
Although Slushpool isn’t one of the very largest pools, it does offer a newbie-friendly interface alongside more advanced features for those that need them. The pool has moderately high fees of 2 percent but offers servers in several countries — including the U.S., Europe, China, and Japan — giving it a good balance of fees to features.
BTC.com is another potential candidate for your pool and currently stands as the largest public Bitcoin mining pool. It is responsible for mining around 17 percent of new blocks. Being the largest public mining pool provides users with a sense of security, ensuring blocks are mined regularly and a stable income is made.

BTC.com is owned by Bitmain, a company that manufacturers mining hardware, and charges a 1.5 percent fees — placing it squarely in the middle-tier in terms of fees. Unlike other platforms, BTC.com uses its own payment structure known as FPPS (Full Pay Per Share), which means miners also receive a share of the transaction fees included within mined blocks — making it slightly more profitable than standard payment per share (PPS) pools.
Another great option is Antpool, a mining pool that supports mining services for 10 different cryptocurrencies, including Bitcoin, Litecoin (LTC) and Ethereum (ETH). AntPool frequently trades places with BTC.com as the largest Bitcoin mining pool. However, as of this writing, it occupies the title of the third-largest public mining pool.
What sets Antpool apart from other pools is the ability to choose your own fee system — including PPS, PPS+, and PPLNS. If you choose PPLNS, using Antpool is free but you will not receive any transaction fees from any blocks mined. Antpool also offers regular payouts and has a low minimum payout of just 0.001 BTC, making it suitable for smaller miners.
Last on the list of the best Bitcoin mining pools in 2019 is the Bitcoin.com mining pool. Although this is one of the smaller pools available, the Bitcoin.com pool has some redeeming features that make it worth a look. It offers mining contracts, allowing you to test out Bitcoin mining before investing in mining equipment of your own. According to Bitcoin.com, they are the highest paying Pay Per Share (PPS) pool in the world, offering up to 98 percent block rewards as well as automatic switching between BTC and BCH mining to optimize profitability.

Electricity Costs
While your mining hardware is most important when it comes to how much BTC you can earn when mining, your electricity costs are usually the largest additional expense. With electricity costs often varying dramatically between countries, ensuring you are on the best cost-per-KWh plan available will help to keep costs down when mining.
Most commonly, large mining operations will be set up in countries where electricity costs are the lowest — such as Iceland, India, and Ukraine. Since China has one of the lowest energy costs in the world, it was previously the epicenter of Bitcoin mining. However, since the government began cracking down on cryptocurrencies, it has largely fallen out of favor with miners.
Technically, Venezuela is one of the cheapest countries in the world in terms of electricity, with the government heavily subsidizing these energy costs — while Bitcoin offers an escape from the hyperinflation suffered by the Venezuelan bolivar. Despite this, importing mining hardware into the country is a costly endeavor, making it impractical for many people.
Finding ways to lower your electricity costs is one of the best ways to improve your mining profitability. This can include investing in renewable energy sources such as solar, geothermal, or wind — which can yield increased profitability over the long term.

What is Blockchain Technology?

What is Blockchain Technology?
The original article appeared here: https://www.securities.io/what-is-blockchain-technology/
Its been almost ten years since Satoshi Nakamoto first introduced Blockchain technology to the world in his 2008 Bitcoin Whitepaper. Since that time, these revolutionary networks have gained popularity in both the corporate and governmental sectors. This growth is easily explained when you consider that blockchain technology provides the world with some unique advantages that were previously unimaginable. Consequently, today, you can find blockchain technology in nearly every sector of the global economy.

What is Blockchain Technology?

A blockchain is a network of computers that share a distributed ledger across all network participants (nodes). This strategy is far different than say, fiat currencies that originate from a centralized authority figure. Importantly, this ledger keeps an unbroken chain of transactions since the birth of the network. This “chain” of transactions grows larger as new “blocks” of transactions are approved and added to it.
Bitcoin Whitepaper
In order to approve new transactions, each node works together with others to validate new blocks. Additionally, the nodes also validate the current state of the entire blockchain. In order for a new block of transactions to be added to the blockchain, they must receive approval from 51% of the network’s nodes. Nodes are also referred to as miners. In this manner, blockchain networks are decentralized networks that provide unmatched security to the world of digital assets.

Security via Decentralization

Decentralization is an important aspect of blockchain technology because it makes these revolutionary ledgers immutable and unalterable. In fact, since there is no centralized attack vector, hacking a blockchain is nearly impossible. The larger the blockchain network, the more secure the data on it remains.
For example, let’s look at the world’s largest blockchain, Bitcoin. Currently, the Bitcoin blockchain has over 10,000 active nodes located across the globe. This distribution means that in order for an attacker to alter even just one tiny piece of information on the blockchain, they would need to successfully hack 5,000+ computers at once.
While this task may not be impossible for the quantum computers of the future, it’s so unprofitable that it makes no sense to even attempt such a monumental task. Additionally, on top of successfully hacking 5000+ computers at once, an attacker would also need a supercomputer to recalculate the new blockchain transactions in time to introduce them into the network. It would literally be more affordable to create a new cryptocurrency from scratch.

Consensus Mechanisms

One of the reasons why blockchain networks are so secure is the integration of consensus mechanisms. Consensus mechanisms are cryptographic protocols that leverage the participants of a blockchain network in securing its data. In the case of Bitcoin, the Proof-of-Work (PoW) consensus mechanism is used.

Proof-of-Work (PoW)

The Proof-of-Work consensus mechanism was revolutionary to the world of cryptography when it was first introduced years prior by Adam Back in his Hashcash whitepaper. In the concept, Back describes the integration of a mathematical equation to the network’s security protocols. In this way, every computer can show “proof” of their work securing the network.

Miner Rewards

It’s important to understand that nodes receive a reward for their mining efforts. These rewards adjust automatically depending on the network’s difficulty and value. In the case of Bitcoin, miners originally received 50 Bitcoin for their efforts. Today, this seems like fortune, but back in 2009, Bitcoin was only worth pennies. As the value of the token rises and the network goes, the mining rewards shrink. Today, Bitcoin miners receive 6.5 BTC if they add the next block to the chain.

SHA-256

Notably, every node validates and secures the blockchain, but only one gets to add the next block of transactions to the network. To determine who the next miner is that gets to add this block, every computer competes in a mathematical race to figure out the PoW equation. In the case of Bitcoin, the equation is known as SHA-256. Importantly, the first SHA algorithm dates back to Hashcash. This early version of the equation was known as SHA-1.
Notably, the SHA-256 equation is so difficult that it’s easier and more efficient for your computer to just make random guesses rather than attempting to figure out the equation directly. The answer to the equation must begin with a predetermined amount of 0s. In the Bitcoin blockchain, the equation’s answer must start with four zeros. However, if the network’s congestion rises, so does the difficulty of these equations. This difficulty adjusts by the addition of another zero at the beginning of the required SHA-256 answer.
Similarly to traditional commodities such as gold, there are costs that are associated with the creation and introduction of these digital assets into the market. These random guesses utilize intense computational power. This power equates to real-world costs such as electricity bills. Studies have shown that securing the Bitcoin network can use more electricity than required by entire countries. Luckily, over 80% of Bitcoin’s power consumption comes from renewable sources such as solar or hydroelectric. This cost of mining also adds measurable value to each Bitcoin.

Miners

As Bitcoin began to gain in profitability, its network’s computing power expanded significantly. In the beginning, nodes, also known as miners, could mine for Bitcoin using nothing more than your home PC. Eventually, miners realized that graphic cards were far better at the repetitive guessing required to figure out the SHA-256 algorithm. This led to a computational race in the market.

ASIC

Eventually, large blockchain firms such as Bitmain introduced Application Specific Integrated Circuit (ASIC) miners into the equation. These purpose-built miners were thousands of times more efficient at guessing the SHA-256 algorithm than the GPUs and CPUs before them. Consequently, their introduction created a scenario in which the average miner now needed to invest thousands in mining equipment to stay relevant.

Mining Pools

Luckily, some creative minds in the field began to think of ways to level the playing field out again. They developed “mining pools.” A mining pool is a network of miners that all share computational power for the common goal of mining blockchain transactions. Importantly, mining pool participants receive a percentage of the reward based on their contributions to the network’s overall hash (computational power).
Importantly, over the last three years, there has been a push to move away from power-hungry consensus mechanisms such as PoW. This desire to secure blockchains in a more efficient manner has led to the development of some truly unique consensus mechanisms in the sector.

Proof-of-Stake (PoS)

The Proof-of-Stake mechanism does away with the difficult mathematical algorithms and instead utilizes a more psychological approach to securing the network. In a PoS blockchain, users don’t need to compete mathematically to add the next block to the blockchain. Instead, PoS users “stake” their coins via network wallets to secure the network. The way staking works is simple.
Keeping a certain amount of coins in your wallet allows you to participate in transaction validations. The more coins you stake, the more likely the chances are you get to add the next block of transactions to the network. In most PoS systems, a miner from those with the most tokens staked at the time receives the chance to add the blocks.
The advantages of a PoS consensus mechanism are immediately evident. For one, you don’t need to pour tons of resources into your network to keep it safe. Additionally, since nodes are chosen based on their amount of staked coins, there is never a scenario in which a node gains anything from validating incorrect transactions. Basically, a hacker would have to fully invest in the cryptocurrency prior to attacking the network. In this way, PoS systems create a huge deterrent to attackers.

The Future of Blockchain Technology

Blockchain technology has come a long way from its early days as a means to secure cryptocurrency networks. Today, blockchain technology has numerous uses across every type of industry imaginable. Specifically, blockchain programs have impacted the logistical, financial, and data security sectors in a major way.

Blockchain Technology Logistics

Blockchain logistical systems are more efficient and cost-effective to operate than traditional paper-based models. In fact, the immutable and unalterable nature of blockchain tech makes it ideally suited to logistical tasks. Soon, you may be able to ascertain much more information regarding the creation and delivery of your products thanks to these new-age systems emerging.

Fundraising

Blockchain technology has also altered the way in which businesses raise funds. In a traditional corporate crowdfunding strategy such as an IPO, companies must balance between cost-effectiveness and participation. The inability to process smaller transactions meant that for the longest time, companies had to turn away potential investors. Nowadays, blockchain technology enables businesses to easily automate these procedures via smart contracts.

Smart Contracts

Smart Contracts feature preprogrammed protocols that execute when they receive a certain amount of cryptocurrency sent to their address. These contracts live on the blockchain and enable remarkable functionality. For example, in the case of fundraising, a smart contract can automate processes such as the approval of investors and the distribution of funds.

Blockchain Technology Today

You can expect to see further expansion of the blockchain sector in the coming months as more governments and institutions explore its benefits. For now, the blockchain revolution is well underway.

ColossusXT and the Colossus Grid will utilize 2 layers of privacy through Obfuscation Zerocoin Protocol, and I2P and these will protect users of the Colossus Grid as they utilize grid resources. There are also Masternodes and Proof of Stake which both can contribute to reducing 51% attacks, along with instant transactions and zero-fee transactions. This protection is paramount as ColossusXT evolves into the Colossus Grid. Grid Computing will have a pivotal role throughout the world, and what this means is that users will begin to experience the Internet as a seamless computational universe. Software applications, databases, sensors, video and audio streams-all will be reborn as services that live in cyberspace, assembling and reassembling themselves on the fly to meet the tasks at hand. Once plugged into the grid, a desktop machine will draw computational horsepower from all the other computers on the grid.
Q: What is the Colossus Grid?
A: ColossusXT is an anonymous blockchain through obfuscation, Zerocoin Protocol, along with utilization of I2P. These features will protect end user privacy as ColossusXT evolves into the Colossus Grid. The Colossus Grid will connect devices in a peer-to-peer network enabling users and applications to rent the cycles and storage of other users’ machines. This marketplace of computing power and storage will exclusively run on COLX currency. These resources will be used to complete tasks requiring any amount of computation time and capacity, or allow end users to store data anonymously across the COLX decentralized network. Today, such resources are supplied by entities such as centralized cloud providers which are constrained by closed networks, proprietary payment systems, and hard-coded provisioning operations. Any user ranging from a single PC owner to a large data center can share resources through Colossus Grid and get paid in COLX for their contributions. Renters of computing power or storage space, on the other hand, may do so at low prices compared to the usual market prices because they are only using resources that already exist.
Q: When will zerocoin be fully integrated?
A: Beta has been released for community testing on Test-Net. As soon as all the developers consider the code ready for Main-Net, it will be released. Testing of the code on a larger test network network will ensure a smooth transition.
Q: Is the end goal for the Colossus Grid to act as a decentralized cloud service, a resource pool for COLX users, or something else?
A: Colossus Grid will act as a grid computing resource pool for any user running a COLX node. How and why we apply the grid to solve world problems will be an ever evolving story.
Q: What do you think the marketing role in colx.? When ll be the inwallet shared nodes available...i know its been stated in roadmap but as u dont follow roadmap and offer everything in advance...i hope shared MN's to be avilable soon.
A: The ColossusXT (COLX) roadmap is a fluid design philosophy. As the project evolves, and our community grows. Our goal is to deliver a working product to the market while at the same time adding useful features for the community to thrive on, perhaps the Colossus Grid and Shared Masternodes will be available both by the end of Q4 2018.
Q: When will your github be open to the public?
A: The GitHub has been open to the public for a few months now.
You can view the GitHub here: https://github.com/ColossusCoinXT
The latest commits here: https://github.com/ColossusCoinXT/ColossusCoinXT/commits/master
Q: Why should I use COLX instead of Monero?
A: ColossusXT offers Proof of Stake and Masternodes both which contribute layers in protection from 51% attacks often attributed with Proof of Work consensus, and in being Proof of Work(Monero) ColossusXT is environmentally friendly compared to Proof of Work (Monero). You can generate passive income from Proof of Stake, and Masternodes. Along with helping secure the network.What really sets ColossusXT apart from Monero, and many other privacy projects being worked on right now, is the Colossus Grid. Once plugged into the Colossus Grid, a desktop machine will draw computational horsepower from all the other computers on the grid. Blockchain, was built on the core value of decentralization and ColossusXT adhere to these standards with end-user privacy in mind in the technology sector.
Q: With so many coins out with little to no purpose let alone a definitive use case, how will COLX distinguish itself from the crowd?
A: You are right, there are thousands of other coins. Many have no purpose, and we will see others “pumping” from day to day. It is the nature of markets, and crypto as groups move from coin to coin to make a quick profit. As blockchain regulations and information is made more easily digestible projects like ColossusXT will rise. Our goal is to produce a quality product that will be used globally to solve technical problems, in doing so grid computing on the ColossusXT network could create markets of its own within utilizing Super-computing resources. ColossusXT is more than just a currency, and our steadfast approach to producing technical accomplishments will not go unnoticed.
Q: Tell the crowd something about the I2P integration plan in the roadmap? 🙂
A: ColossusXT will be moving up the I2P network layer in the roadmap to meet a quicker development pace of the Colossus Grid. The I2P layer will serve as an abstraction layer further obfuscating the users of ColossusXT (COLX) nodes. Abstraction layer allows two parties to communicate in an anonymous manner. This network is optimised for anonymous file-sharing.
Q: What kind of protocols, if any, are being considered to prevent or punish misuse of Colossus Grid resources by bad actors, such as participation in a botnet/denial of service attack or the storage of stolen information across the Grid?
A: What defines bad actors? ColossusXT plans on marketing to governments and cyber security companies globally. Entities and individuals who will certainly want their privacy protected. There is a grey area between good and bad, and that is something we can certainly explore as a community. Did you have any ideas to contribute to this evolving variable?What we mean when we say marketing towards security companies and governments is being utilized for some of the projects and innovating new ways of grid computing.

Governments: https://www.techwalla.com/articles/what-are-the-uses-of-a-supercomputer
Q: The Colossus Grid is well defined but I don't feel easily digestible. Has their been any talk of developing an easier to understand marketing plan to help broaden the investoadoptor base?
A: As we get closer to the release of the Colossus Grid marketing increase for the Colossus Grid. It will have a user friendly UI, and we will provide Guides and FAQ’s with the release that any user intending to share computing power will be able to comprehend.
Q: Can you compare CollossusXT and Golem?
A: Yes. The Colosssus Grid is similar to other grid computing projects. The difference is that ColossusXT is on it’s own blockchain, and does not rely on the speed or congestion of a 3rd party blockchain. The Colossus Grid has a privacy focus and will market to companies, and individuals who would like to be more discreet when buying or selling resources by offering multiple levels of privacy protections.
Q: How do you guys want to achieve to be one of the leaders as a privacy coin?
A: Being a privacy coin leader is not our end game. Privacy features are just a small portion of our framework. The Colossus Grid will include privacy features, but a decentralized Supercomputer is what will set us apart and we intend to be leading this industry in the coming years as our vision, and development continue to grow and scale with technology.
Q: With multiple coins within this space, data storage and privacy, how do you plan to differentiate COLX from the rest? Any further partnerships planned?
A: The Colossus Grid will differentiate ColossusXT from coins within the privacy space. The ColossusXT blockchain will differentiate us from the DATA storage space. Combining these two features with the ability to buy and sell computing power to complete different computational tasks through a decentralized marketplace. We intend to involve more businesses and individuals within the community and will invite many companies to join in connecting the grid to utilize shared resources and reduce energy waste globally when the BETA is available.
Q: Has colossus grid had the best come up out of all crypto coins?
A: Possibly. ColossusXT will continue to “come up” as we approach the launch of the Colossus Grid network.
Q: How far have Colossus gone in the ATM integration
A: ColossusXT intends to and will play an important role in the mass adoption of cryptocurrencies. We already have an ongoing partnership with PolisPay which will enable use of COLX via master debit cards. Along with this established relationship, ColossusXT team is in touch with possible companies to use colx widely where these can only be disclosed upon mutual agreement.
Q: How does COLX intend to disrupt the computing industry through Grid Computing?
A: Using the Colossus Grid on the ColossusXT blockchain, strengthens the network. Computers sit idly by for huge portions of the day. Connecting to the Colossus Grid and contributing those idle resources can make use of all the computing power going to waste, and assist in advancing multiple technology sectors and solving issues. Reducing costs, waste, and increased speed in technology sectors such as scientific research, machine learning, cyber security, and making it possible for anyone with a desktop PC to contribute resources to the Colossus Grid and earn passive income.
Q: What kind of partnerships do you have planned and can you share any of them? :)
A: The ColossusXT team will announce partnerships when they are available. It’s important to finalize all information and create strong avenues of communication between partners ColossusXT works with in the future. We are currently speaking with many different exchanges, merchants, and discussing options within our technology sector for utilizing the Colossus Grid.
Q: Will shared Masternodes be offered by the COLX team? Or will there be any partnerships with something like StakingLab, StakeUnited, or SimplePosPool? StakingLab allows investors of any size to join their shared Masternodes, so any investor of any size can join. Is this a possibility in the future?
A: ColossusXT has already partnered with StakingLab. We also plan to implement shared Masternodes in the desktop wallet.
Q: How innovative is the Colossus Grid in the privacy coin space?
A: Most privacy coins are focused on being just a currency / form of payment. No other project is attempting to do what we are doing with a focus on user privacy.
Q: Hey guys do you think to integrated with some other plataforms like Bancor? I would like it!
A: ColossusXT is in touch with many exchange platforms, however, due to non disclosure agreements details cannot be shared until it is mutually decided with the partners. We will always be looking for new platforms to spread the use of colx in different parts of the world and crypto space.
Q: What is the reward system for the master node owners?
A: From block 388.800 onwards, block reward is 1200 colx and this is split based on masternode ownestaker ratio. This split is based on see-saw algorithm. With an increasing number of masternodes the see-saw algorithm disincentivizes the establishment of even more masternodes because it lowers their profitability. To be precise, as soon as more than 41.5% of the total COLX coin supply is locked in masternodes, more than 50% of the block reward will be distributed to regular staking nodes. As long as the amount of locked collateral funds is below the threshold of 41.5%, the see-saw algorithm ensure that running a masternode is financially more attractive than running a simple staking node, to compensate for the additional effort that a masternode requires in comparison to a simple staking node.Please refer to our whitepaper for more information.
Q: What other marketplaces has the COLX team been in contact with?
Thanks guys! Love the coin and staff
A: ColossusXT gets in touch for different platforms based on community request and also based on partnership requests received upon ColossusXT business team’s mutual agreement. Unfortunately, these possibilities cannot be shared until they are mutually agreed between the partners and ColossusXT team due to non disclosure agreements.
Q: What do you think about the new rules that will soon govern crypto interactions in the EU? they are against anonymous payments
A: Blockchain technology is just now starting to become clear to different governments.
ColossusXT's privacy features protect the end-user from oversharing personal information. As you are probably aware from the multiple emails you've received recently from many websites.
Privacy policies are always being updated and expanded upon. The use of privacy features with utility coins like ColossusXT should be a regular norm throughout blockchain. This movement is part is about decentralization as much as it is about improving technology.
While this news may have a role to play. I don't think it is THE role that will continuously be played as blockchain technology is implemented throughout the world.
Q: Any hints on the next big feature implementation you guys are working on? According to road map - really excited to hear more about the Shared MN and the scale of the marketplace!
A: Current work is focused on the privacy layer of Colossus Grid and completing the updated wallet interface.
Q: Why choose COLX, or should I say why should we believe in COLX becoming what you promise in the roadmap. What are you different from all the other privacy coins with block chain establishment already in effect?
A: ColossusXT is an environmentally friendly Proof of Stake, with Masternode technology that provide dual layers of protection from 51% attacks. It includes privacy features that protect the user while the utilize resources from the Colossus Grid. Some of the previous questions within this AMA may also answer this question.
Q: What tradeoffs do you have using the Colossus Grid versus the more typical distribution?
A: The advantage of supercomputers is that since data can move between processors rapidly, all of the processors can work together on the same tasks. Supercomputers are suited for highly-complex, real-time applications and simulations. However, supercomputers are very expensive to build and maintain, as they consist of a large array of top-of-the-line processors, fast memory, custom hardware, and expensive cooling systems. They also do not scale well, since their complexity makes it difficult to easily add more processors to such a precisely designed and finely tuned system.By contrast, the advantage of distributed systems (Like Colossus Grid) is that relative to supercomputers they are much less expensive. Many distributed systems make use of cheap, off-the-shelf computers for processors and memory, which only require minimal cooling costs. In addition, they are simpler to scale, as adding an additional processor to the system often consists of little more than connecting it to the network. However, unlike supercomputers, which send data short distances via sophisticated and highly optimized connections, distributed systems must move data from processor to processor over slower networks making them unsuitable for many real-time applications.
Q: Why should I choose Colossus instead of another 100,000 altcoins?
A: Many of these alt-coins are all very different projects. ColossusXT is the only Grid computing project with a focus on user privacy. We have instant transactions, and zero-fee transactions and ColossusXT is one of the very few coins to offer live support. Check out our Whitepaper!
Q: Will there be an option (in the future) to choose between an anonymous or public transaction?
A: Zerocoin is an evolution of the current coin mixing feature. Both allow an individual to decide how they would like to send their transactions.
Q: What exchange has highest volume for ColossusXT, and are there any plans for top exchanges soon ?
A: Currently Cryptopia carries the majority of ColossusXT volume. We are speaking with many different exchanges, and preparing requested documentation for different exchanges. ColossusXT intends to be traded on every major exchange globally.
Q: What is the TPS speed that colx blockchain achieves?
A: ColossusXT achieves between 65-67 TPS depending on network conditions currently.
Q: Plans on expanding the dev team?
A: As development funds allow it, the team will be expanded. Development costs are high for a unique product like ColossusXT, and a good majority of our budget is allocated to it.
Q: Can you explain what is and what are the full porpose of the COLOSSUSXT GRID PROJECT ?
A: Colossus Grid is explained in the whitepaper. The uses for grid computing and storage are vast, and we are only starting to scratch the surface on what this type of computing power can do. There is also a description within the formatting context within the AMA of the Colossus Grid.
Q: Is there mobile wallet for Android and iOS? If not, is there a roadmap?
A: There Android wallet is out of beta and on the Google PlayStore: iOS wallet is planned for development.
The roadmap can be found here: https://colossusxt.io/roadmap/
Q: Is ColossusXT planning on partnering up with other cryptocurrency projects? Such as: Bread and EQUAL.
A: ColossusXT plans on partnering with other crypto projects that make sense. We look for projects that can help alleviate some of our development work / provide quality of life upgrades to our investors so that we can focus on Colossus Grid development. When absolutely love it when the community comes to us with great projects to explore.
Q: Did you ever considered a coinburn? Don't you think a coin burn will increase COLX price and sustain mass adoption? Do you plan on keeping the price of COLX in a range so the potential big investors can invest in a not so much volatile project?
A**:** There are no plans to do a coinburn at this time. Please check out our section in the whitepaper about the supply.
Q: what is the next big exchange for colx to be listed ?
A: There are several exchanges that will be listing ColossusXT soon. Stay tuned for updates within the community as some have already been announced and future announcements.
  1. CryptalDash
  2. NextExchange
  3. CoinPulse
  4. CoinSwitch (Crowdfunding)
  5. Plaak (Crowdfunding)
Q: How will Colx compete with other privacy coins which claim to be better like Privacy?
A: ColossusXT is not competing with other privacy coins. ColossusXT will evolve into the Colossus Grid, which is built on the backbone of a privacy blockchain. In our vision, all these other privacy coins are competing for relevancy with ColossusXT. There are also similar responses to question that may hit on specifics.
Q: Does COLX have a finite number of coins like bitcoin?
A: No, ColossusXT is Proof of Stake. https://en.wikipedia.org/wiki/Proof-of-stake
Q: What are the advantages of COLX over other competitor coins (eg. ECA)?
A: The only similarities between ColossusXT and Electra is that we are both privacy blockchains. ColossusXT is very much an entirely different project that any other privacy coin in the blockchain world today. The Colossus Grid will be a huge advantage over any other privacy coin. Offering the ability for a desktop machine to rent power from others contributing to the Colossus Grid and perform and compute high level tasks.
Q: How do you feel about some countries frowning upon privacy coins and how do you plan to change their minds (and what do you plan to do about it?)
A: The ColossusXT team tries to view opinions from multiple perspectives so that we can understand each line of thinking. As blockchain technology becomes more widely adopted, so will the understanding of the importance of the privacy features within ColossusXT. Privacy is freedom.
Q: How do you see COLX in disrupting cloud gaming services such as PlayStation Now?
A: Cloud gaming services have not been discussed. Initial marketing of our private grid computing framework will be targeted at homes users, governments, and cyber security firms who may require more discretion / anonymity in their work.
Q: Since colx is a privacy coin and is known for its privacy in the transactions due to which lot of money laundering and scams could take place, would colx and its community be affected due to it? And if does then how could we try to prevent it?
A: ColossusXT intends to be known for the Colossus Grid. The Colossus Grid development will be moved up from Q1 2019 to Q3 2018 to reflect this message and prevent further miscommunication about what privacy means for the future of ColossusXT. Previous answers within this AMA may further elaborate on this question.
Q: When do you plan to list your coin on other "bigger" exchanges?
A: ColossusXT is speaking with many different exchanges. These things have many different factors. Exchanges decide on listing dates and we expect to see ColossusXT listed on larger exchanges as we approach the Colossus Grid Beta. The governance system can further assist in funding.
Q: What was the rationale behind naming your coin ColossusXT?
A: Colossus was a set of computers developed by British codebreakers in the years 1943–1945. XT symbolises ‘extended’ as the coin was forked from the original Cv2 coin.
Q: Can you give any details about the E Commerce Marketplace, and its progress?
A: The Ecommerce Marketplace is a project that will receive attention after our development pass on important privacy features for the grid. In general, our roadmap will be changing to put an emphasis on grid development.
Q: How will someone access the grid, and how will you monetize using the grid? Will there be an interface that charges COLX for time on the grid or data usage?
A: The Colossus Grid will be integrated within the ColossusXT wallet. Buying & Selling resources will happen within the wallet interface. You won't be able to charge for "time" on the grid, and have access to unlimited resources. The goal is to have users input what resources they need, and the price they are willing to pay. The Colossus Grid will then look for people selling resources at a value the buyer is willing to pay. Time may come into play based on which resources you are specifically asking for.
Q: Are there any plans to launch an official YouTube channel with instructional videos about basic use of the wallets and features of COLX? Most people are visually set and learn much faster about wallets when actually seeing it happen before they try themselves. This might attract people to ColossusXT and also teach people about basic use of blockchain and cryptocurrency wallets. I ask this because I see a lot of users on Discord and Telegram that are still learning and are asking a lot of real basic questions.
A: ColossusXT has an official YT account with instructional videos: https://www.youtube.com/channel/UCCmMLUSK4YoxKvrLoKJnzng
Q: What are the usp's of colx in comparing to other privacy coins?
A: Privacy coins are a dime a dozen. ColossusXT has different end goals than most privacy coins, and this cannot be stated enough. Our goal is not just to be another currency, but to build a sophisticated computing resource sharing architecture on top of the privacy blockchain.
Q: A new exchange will probably gain more liquidity for our coin. If you might choose 3 exchanges to get COLX listed, what would be your top 3?
A: ColossusXT intends to be listed on all major exchanges globally. :)
Q: What is the future of privacy coins? What will be the future colx userbase (beyond the first adopters and enthusiasts)?
A: The future of privacy is the same it has always been. Privacy is something each and everyone person owns, until they give it away to someone else. Who is in control of your privacy? You or another person or entity?The future of the ColossusXT user base will comprise of early adopters, enthusiast, computer science professionals, artificial intelligence, and computational linguistics professionals for which these users can utilize the Colossus Grid a wide range of needs.
Q: Will ColossusXT join more exchanges soon??
A: Yes. :)
Q: So when will Colossus put out lots of advertisement to the various social media sites to get better known? Like Youtube videos etc.
A: As we get closer to a product launch of the Colossus Grid, you’ll begin to see more advertisements, YouTubers, and interviews. We’re looking to also provide some presentations at blockchain conferences in 2018, and 2019.
Q: In your opinion, what are some of the issues holding COLX back from wider adoption? In that vein, what are some of the steps the team is considering to help address those issues?
A: One of the main issues that is holding ColossusXT back from a wider adoption is our endgame is very different from other privacy coins. The Colossus Grid. In order to address this issue, the ColossusXT team intends to have a Colossus Grid Beta out by the end of Q4 and we will move development of the Colossus Grid from Q1 2019 to Q3 2018.
Q: Or to see it from another perspective - what are some of the biggest issues with crypto-currency and how does COLX address those issues?
A: Biggest issue is that cryptocurrency is seen as a means to make quick money, what project is going to get the biggest “pump” of the week, and there is not enough focus on building blockchain technologies that solve problems or creating legitimate business use cases.
For the most part we believe the base of ColossusXT supporters see our end-game, and are willing to provide us with the time and support to complete our vision. The ColossusXT team keeps its head down and keeps pushing forward.
Q: I know it's still early in the development phase but can you give a little insight into what to look forward to regarding In-wallet voting and proposals system for the community? How much power will the community have regarding the direction COLX development takes in the future?
A: The budget and proposal system is detailed in the whitepaper. Masternode owners vote on and guide the development of ColossusXT by voting on proposals put forth by the community and business partners.
Our goal is to make this process as easy and accessible as possible to our community.
Q: Will there be an article explaining the significance of each partnership formed thus far?
A: Yes, the ColossusXT team will announce partners on social media, and community outlets. A detailed article of what partnerships mean will be available on our Medium page: https://medium.com/@colossusxt
Q: What potential output from the Grid is expected and what would it's use be?
For example, x teraflops which could process y solutions to protein folding in z time.
A: There are many uses for grid computing. A crypto enthusiast mining crypto, a cyber security professional cracking a password using brute force, or a scientist producing climate prediction models.
The resources available to put towards grid projects will be determined by the number of nodes sharing resources, and the amount of resources an individual is willing to purchase with COLX.
All individuals will not have access to infinite grid resources.
Q: Is there a paper wallet available?
A: Yes, see https://mycolxwallet.org
Q: Is there a possibility of implementing quantum computer measures in the future?
A: This is a great idea for potentially another project in the future. Currently this is not possible with the Colossus Grid. Instead of bits, which conventional computers use, a quantum computer uses quantum bits—known as qubits. In classical computing, a bit is a single piece of information that can exist in two states – 1 or 0. Quantum computing uses quantum bits, or 'qubits' instead. These are quantum systems with two states. However, unlike a usual bit, they can store much more information than just 1 or 0, because they can exist in any superposition of these values.
Q: Do you plan to do a coin burn?
A: No future coin burns are planned. Anything like this would go through a governance proposal and Masternode owners would vote on this. This is not anything we’ve seen within the community being discussed.
Q: Can I check the exact number of current COLX master node and COLX staking node?
A: Yes. You can view the Masternodes and the amount of ColossusXT (COLX) being staked by viewing the block explorer.
Block explorer: https://chainz.cryptoid.info/colx/#!extraction
Q: What incentive could we give a youtuber to do the BEST video of ColossusXT (COLX)?
A: We've been approached by several YouTubers. The best thing a YouTuber can do is understand what ColossusXT is, join the community, ask questions if there is something they don't understand.
The problem with many YouTubers is that some of them are just trying to get paid, they don't really care to provide context or research a project.
Disclaimer: This is not all YouTubers, but many.
Q: In which ways is the ColossusGrid different from other supercomputer / distributed computing projects out there. Golem comes to mind. Thanks!
A: The main difference is that we are focused on the end users privacy, and the types of users that we will be targeting will be those that need more discretion / anonymity in their work. We are building framework that will continue to push the boundaries of user privacy as it relates to grid computing.
Q: Can we please complete our roadmap ahead of schedule? I find most other coins that do this actually excell in terms of price and community members. Keep on top of the game :)
A: The Colossus XT roadmap is a very fluid document, and it is always evolving. Some items are moved up in priority, and others are moved back. The roadmap should not be thought of something that is set in stone.
Q: Does COLX have master nodes?
A: Yes. ColossusXT has masternodes.
Q: Have thought about providing a method to insert a form of payment in colx in any page that wants to use cryptocurrencies in a fast and simple way in order to masive adoption????
A: There is already this option.https://mycryptocheckout.com/coins/
Q: What do you think your community progress till now?
A: The community has grown greatly in the last 3 months. We’re very excited to go from 13 to 100 questions in our quarterly AMA. Discord, Telegram, and Twitter are growing everyday.
Q: I noticed on Roadmap: Coinomi and ahapeshift wallet integration. Can you tell me more about this? I am new in crypto and new ColX investor so I don't know much about this. Thanks and keep a good work.
A: Coinomi is a universal wallet. ColossusXT will have multiple wallet platforms available to it. Shapeshift allows you to switch one crypto directly for another without the use of a coupler (BTC).
Q: Is "A general-purpose decentralized marketplace" written in the whitepaper the same as "E-COMMERCE MARKETPLACE" written on the roadmap?
Please tell me about "A general-purpose decentralized marketplace" or "E-COMMERCE MARKETPLACE" in detail.
A: Details will be posted as we get closer to the marketplace. It will be similar to other marketplaces within blockchain. Stay tuned for more information by following us on Twitter.
Q: History has shown that feature-based technologies always get replaced by technologies with platforms that incorporate those features; what is colossius big picture?
A: The Colossus Grid. Which has been explained within this AMA in a few different ways.
Q: What are the main objectives for COLX team this year? Provide me 5 reason why COLX will survive in a long term perspective? Do you consider masternodes working in a private easy to setup wallet on a DEX network? Already big fan, have a nice day!
A: Getting into Q3 our main object is to get a working product of the Colossus Grid by the end of Q4.
  1. Community - Our community is growing everyday as knowledge about what we’re building grows. When the Colossus Grid is online we expect expansion to grow at a rapid pace as users connect to share resources.
  2. Team - The ColossusXT team will continue to grow. We are stewards of a great community and an amazing project. Providing a level of support currently unseen in many other projects through Discord. The team cohesion and activity within the community is a standard we intend to set within the blockchain communities.
  3. Features - ColossusXT and The Colossus Grid will have user friendly AI. We understand the difficulties when users first enter blockchain products. The confusion between keys, sending/receiving addresses, and understanding available features within. Guides will always be published for Windows/Mac/Linux with updates so that these features can be easily understood.
  4. Colossus Grid - The Colossus Grid answers real world problems, and provides multiple solutions while also reducing energy consumption.
  5. Use Case - Many of the 1000+ other coins on the market don’t have the current use-case that ColossusXT has, let alone the expansion of utility use-cases in multiple sectors.
Q: Will the whitepaper be available in Portuguese?
A: Yes. We will be adding some language bounties to the website in the future. Stay tuned.
Q: Notice in your white paper there are future plans for decentralised governance and masternode voting. While all that is great, how do you plan on mitigating malicious proposals from getting through by gaming the system (i.e. bot votes, multiple accounts, spam,etc)?
A: You cannot game the system. Masternode owners get 1 vote.
Q: Been a massive fan of this project since Dec last year, anyways what was the reason you guys thought of putting XT at the end of Colossus. :)
A: XT symbolizes ‘extended’ as the coin was forked from the original Cv2 coin.
Q: Do you plan a partnership within the banking industry to capitalize on such large amounts of money being moved continuously?
A: The focus will be on the Colossus Grid and Grid computing, with the option to participate in the financial sector of Blockchain through Polis Pay, and other partnerships that can be announced in the future.
Q: When will be COLX supported By The Ledger Wallet?
A: Integration with cold storage wallet is planned. I myself (PioyPioyPioy) have a Nano Ledger S and I love it!
Q: Where do you see yourself in five years?
A: The goal 5 years from now would be to be a leading competitor in cloud computing and storage. Providing government, private cybersecurity, and individuals with efficient solutions to Super-computing, cloud storage through Blockchain infrastructure. I would like to see hardware options of connecting to the grid to utilize resources after the Colossus Grid is online, and I think this can contribute to many use-case scenarios.
Q: How can I suggest business partnerships and strategic ideas etc to the ColossusXT team?
A: Join us in Discord. Members of the team here are active daily, you can also contact us at: [[email protected]](mailto:[email protected])
Q: A great project requires good funding. How do you plan to incorporate fund sourcing and management into the long-term planning of this project
A: Check out our governance section within the whitepaper. :)
