Hulk.Finance: A Combination of DeFi and High Frequency Trading

DeFi continues to push the limits of blockchain technology. Whether its staking a native token for a second token from the same ecosystem, locking liquidity for an eternity to promote liquidity providing and the benefits of locking tokens, or simply creating new tokenomics that can be tested and studied, DeFi is exploring all avenues to produce the next breakout token such as YFI. Hulk.finance has stepped in to do just that.

Hulk.finance (Contract Address: 0xE1f8CD01aB04b51d02C6fb2BCA61B03fB5e33B99**)** is an ERC20 token which plans to utilize a DAO (Decentralized Autonomous Organization) format that will be community governed in order to promote high frequency trading in a manner only DeFi can bring to the table. As stated on their website, “Our project connects a high-yield partner HFT (High Frequency Trading) fund that has successfully worked from the beginning of 2020 and has year-to-date yields of more than 40%. The fund size is more than 70 millions USD and they operate on several cryptocurrency exchanges like Binance and Bithumb with their API robots. What is good — automated trading does not require continuous uptrend of the Bitcoin price. We have seen good results during Bitcoin breakouts and breakdowns. We want to have the same yields from our investments. But there is a problem — they work with an entrance barrier of 1,000,000 USDT, like many private banking services or high-yield ETFs. Our basic idea is to make a kind of DeFi staking pool and put it under the management of the HFT fund. We will develop all infrastructure for connecting finance flows, deposits, and withdrawals.

The HULK total supply is 100,000 Tokens. Distribution breakdown is as follows:

The project is new but already has a road-map to help guide their lofty ambitions. The first step begins with the formation of the pre-sale and Liquidity pool on Uniswap which is currently ongoing. Secondly, they will distribute Hulk tokens via staking farms. As described in their website they “will run staking farms for farming 80,000 HULKs*. You will need to stake appropriate tokens on the selected farms to get your share of rewards in HULKs. Farm 1 will farm rewards of 60,000* HULKs within 15 days, staking token — ETH-HULK LP Uniswap V2. Farm 2 will farm rewards of 10,000 HULKs within 15 days, staking token — USDN. Farm 3 will farm rewards of 10,000 HULKs within 15 days, staking token — Token Y. Token Y will be announced prior to the farms’ launch. Genesis farming time will be 15 days, after that farming rate will be settled on the level of 15th day. We implement halving every three days, so early farmers will get more HULKs. View on Etherscan. In order to support the price of the token from dumping, we will take a 5% commission for the sale of tokens, when holders sell it on Uniswap, burn 4% and add 1% to the community grants account. The burnt amount will be added to farming pools after 15 days of initial farming. So, for example, if someone sold 20,000 HULKs, we will take 1,000 tokens, burn 800 of them and they will be re-minted on day 16. 200 tokens will be sent to the community grants address. The total supply is 100,000 tokens.”

The third step includes the staking pool. The staking pool will be open for everyone on the following terms and conditions.


Funds from the staking pool will be transferred to the HFT fund for trading operations.

Lastly, the Vault concept is descriptive. “We want to share revenue from HFT fund among HULK holders that stake their tokens in HULK Vault. HFT fund will send revenue from its operation once a month, on the first day of the following month. Current concept: Monthly revenue from HFT operations will be shared between HULK tokens staked in the vault according to the time of staking divided on 720 hours. Example: You stake your 500 HULK tokens in Vault for 20 days (480 hours). Your HULK/hours equal to 500*480=240,000. Total HULK/hours in Vault in this month — 60,000,000. Your share in this month = 0,4%. HFT fund has earned 4% on staking pool funds this month. After payout of their 1,25% (15%/12) per month to USDT stakers, the remaining part is 10,000,000 USDT x 2,75% = 275,000 USD. Your profit share 0.4% of 275,000 = 1100 USDT will be sent as USDT to your address, connected with a Vault.”

All of the above described by the tokens creators seems very complicated, but many tokens are already trying to accomplish this without access to an already built fund which can execute trades on a daily basis. Also due in part is the projects commitment to becoming a DAO by allowing holders to vote on key project decisions and development to make the ecosystem more effective and manageable. Decentralization is the most trustworthy base of contract/cryptocurrency ownership. It creates a unique and secure environment free from direct outside influence due to the filter of the entire community being involved. The developers have said that the voting system for the project will be done within the first 30 days of project launch.

With lofty ambition and high expectations, the project looks to capitalize on the DeFi boom by hedging their fund against the market and giving holders a share of the pie. It will be interesting to see how successful and sustainable the project can be, but we will find out soon enough.

Best General RenVM Questions of January 2020

Best General RenVM Questions of January 2020

‌*These questions are sourced directly from Telegram
Q: When you say RenVM is Trustless, Permissionless, and Decentralized, what does that actually mean?
A: Trustless = RenVM is a virtual machine (a network of nodes, that do computations), this means if you ask RenVM to trade an asset via smart contract logic, it will. No trusted intermediary that holds assets or that you need to rely on. Because RenVM is a decentralized network and computes verified information in a secure environment, no single party can prevent users from sending funds in, withdrawing deposited funds, or computing information needed for updating outside ledgers. RenVM is an agnostic and autonomous virtual broker that holds your digital assets as they move between blockchains.
Permissionless = RenVM is an open protocol; meaning anyone can use RenVM and any project can build with RenVM. You don't need anyone's permission, just plug RenVM into your dApp and you have interoperability.
Decentralized = The nodes that power RenVM ( Darknodes) are scattered throughout the world. RenVM has a peak capacity of up to 10,000 Darknodes (due to REN’s token economics). Realistically, there will probably be 100 - 500 Darknodes run in the initial Mainnet phases, ample decentralized nonetheless.

Q: Okay, so how can you prove this?
A: The publication of our audit results will help prove the trustlessness piece; permissionless and decentralized can be proven today.
Permissionless = https://github.com/renproject/ren-js
Decentralized = https://chaosnet.renproject.io/

Q: How does Ren sMPC work? Sharmir's secret sharing? TSS?
A: There is some confusion here that keeps arising so I will do my best to clarify.TL;DR: *SSS is just data. It’s what you do with the data that matters. RenVM uses sMPC on SSS to create TSS for ECDSA keys.*SSS and TSS aren’t fundamental different things. It’s kind of like asking: do you use numbers, or equations? Equations often (but not always) use numbers or at some point involve numbers.
SSS by itself is just a way of representing secret data (like numbers). sMPC is how to generate and work with that data (like equations). One of the things you can do with that work is produce a form of TSS (this is what RenVM does).
However, TSS is slightly different because it can also be done *without* SSS and sMPC. For example, BLS signatures don’t use SSS or sMPC but they are still a form of TSS.
So, we say that RenVM uses SSS+sMPC because this is more specific than just saying TSS (and you can also do more with SSS+sMPC than just TSS). Specifically, all viable forms of turning ECDSA (a scheme that isn’t naturally threshold based) into a TSS needs SSS+sMPC.
People often get confused about RenVM and claim “SSS can’t be used to sign transactions without making the private key whole again”. That’s a strange statement and shows a fundamental misunderstanding about what SSS is.
To come back to our analogy, it’s like saying “numbers can’t be used to write a book”. That’s kind of true in a direct sense, but there are plenty of ways to encode a book as numbers and then it’s up to how you interpret (how you *use*) those numbers. This is exactly how this text I’m writing is appearing on your screen right now.
SSS is just secret data. It doesn’t make sense to say that SSS *functions*. RenVM is what does the functioning. RenVM *uses* the SSSs to represent private keys. But these are generated and used and destroyed as part of sMPC. The keys are never whole at any point.

Q: Thanks for the explanation. Based on my understanding of SSS, a trusted dealer does need to briefly put the key together. Is this not the case?
A: Remember, SSS is just the representation of a secret. How you get from the secret to its representation is something else. There are many ways to do it. The simplest way is to have a “dealer” that knows the secret and gives out the shares. But, there are other ways. For example: we all act as dealers, and all give each other shares of our individual secret. If there are N of us, we now each have N shares (one from every person). Then we all individually add up the shares that we have. We now each have a share of a “global” secret that no one actually knows. We know this global secret is the sum of everyone’s individual secrets, but unless you know every individual’s secret you cannot know the global secret (even though you have all just collectively generates shares for it). This is an example of an sMPC generation of a random number with collusion resistance against all-but-one adversaries.

Q: If you borrow Ren, you can profit from the opposite Ren gain. That means you could profit from breaking the network and from falling Ren price (because breaking the network, would cause Ren price to drop) (lower amount to be repaid, when the bond gets slashed)
A: Yes, this is why it’s important there has a large number of Darknodes before moving to full decentralisation (large borrowing becomes harder). We’re exploring a few other options too, that should help prevent these kinds of issues.

Q: What are RenVM’s Security and Liveliness parameters?
A: These are discussed in detail in our Wiki, please check it out here: https://github.com/renproject/ren/wiki/Safety-and-Liveliness#analysis

Q: What are the next blockchain under consideration for RenVM?
A: These can be found here: https://github.com/renproject/ren/wiki/Supported-Blockchains

Q: I've just read that Aztec is going to be live this month and currently tests txs with third parties. Are you going to participate in early access or you just more focused on bringing Ren to Subzero stage?
A: At this stage, our entire focus is on Mainnet SubZero. But, we will definitely be following up on integrating with AZTEC once everything is out and stable.

Q: So how does RenVM compare to tBTC, Thorchain, WBTC, etc..?
A: An easy way to think about it is..RenVM’s functionality is a combination of tBTC (+ WBTC by extension), and Thorchain’s (proposed) capabilities... All wrapped into one. Just depends on what the end-user application wants to do with it.

Q1: What are the core technical/security differences between RenVM and tBTC?A1: The algorithm used by tBTC faults if even one node goes offline at the wrong moment (and the whole “keep” of nodes can be penalised for this). RenVM can survive 1/3rd going offline at any point at any time. Advantage for tBTC is that collusion is harder, disadvantage is obviously availability and permissionlessness is lower.
tBTC an only mint/burn lots of 1 BTC and requires an on-Ethereum SPV relay for Bitcoin headers (and for any other chain it adds). No real advantage trade-off IMO.
tBTC has a liquidation mechanism that means nodes can have their bond liquidated because of ETH/BTC price ratio. Advantage means users can get 1 BTC worth of ETH. Disadvantage is it means tBTC is kind of a synthetic: needs a price feed, needs liquid markets for liquidation, users must accept exposure to ETH even if they only hold tBTC, nodes must stay collateralized or lose lots of ETH. RenVM doesn’t have this, and instead uses fees to prevent becoming under-collateralized. This requires a mature market, and assumed Darknodes will value their REN bonds fairly (based on revenue, not necessarily what they can sell it for at current —potentially manipulated—market value). That can be an advantage or disadvantage depending on how you feel.
tBTC focuses more on the idea of a tokenized version of BTC that feels like an ERC20 to the user (and is). RenVM focuses more on letting the user interact with DeFi and use real BTC and real Bitcoin transactions to do so (still an ERC20 under the hood, but the UX is more fluid and integrated). Advantage of tBTC is that it’s probably easier to understand and that might mean better overall experience, disadvantage really comes back to that 1 BTC limit and the need for a more clunky minting/burning experience that might mean worse overall experience. Too early to tell, different projects taking different bets.
tBTC supports BTC (I think they have ZEC these days too). RenVM supports BTC, BCH, and ZEC (docs discuss Matic, XRP, and LTC).
Q2: This are my assumed differences between tBTC and RenVM, are they correct? Some key comparisons:
-Both are vulnerable to oracle attacks
-REN federation failure results in loss or theft of all funds
-tBTC failures tend to result in frothy markets, but holders of tBTC are made whole
-REN quorum rotation is new crypto, and relies on honest deletion of old key shares
-tBTC rotates micro-quorums regularly without relying on honest deletion
-tBTC relies on an SPV relay
-REN relies on federation honesty to fill the relay's purpose
-Both are brittle to deep reorgs, so expanding to weaker chains like ZEC is not clearly a good idea
-REN may see total system failure as the result of a deep reorg, as it changes federation incentives significantly
-tBTC may accidentally punish some honest micro-federations as the result of a deep reorg
-REN generally has much more interaction between incentive models, as everything is mixed into the same pot.
-tBTC is a large collection of small incentive models, while REN is a single complex incentive model
A2: To correct some points:
The oracle situation is different with RenVM, because the fee model is what determines the value of REN with respect to the cross-chain asset. This is the asset is what is used to pay the fee, so no external pricing is needed for it (because you only care about the ratio between REN and the cross-chain asset).
RenVM does rotate quorums regularly, in fact more regularly than in tBTC (although there are micro-quorums, each deposit doesn’t get rotated as far as I know and sticks around for up to 6 months). This rotation involves rotations of the keys too, so it does not rely on honest deletion of key shares.
Federated views of blockchains are easier to expand to support deep re-orgs (just get the nodes to wait for more blocks for that chain). SPV requires longer proofs which begins to scale more poorly.
Not sure what you mean by “one big pot”, but there are multiple quorums so the failure of one is isolated from the failures of others. For example, if there are 10 shards supporting BTC and one of them fails, then this is equivalent to a sudden 10% fee being applied. Harsh, yes, but not total failure of the whole system (and doesn’t affect other assets).
Would be interesting what RenVM would look like with lots more shards that are smaller. Failure becomes much more isolated and affects the overall network less.
Further, the amount of tBTC you can mint is dependent on people who are long ETH and prefer locking it up in Keep for earning a smallish fee instead of putting it in Compound or leveraging with dydx. tBTC is competing for liquidity while RenVM isn't.

Q: I understand correctly RenVM (sMPC) can get up to a 50% security threshold, can you tell me more?
A: The best you can theoretically do with sMPC is 50-67% of the total value of REN used to bond Darknodes (RenVM will eventually work up to 50% and won’t go for 67% because we care about liveliness just as much as safety). As an example, if there’s $1M of REN currently locked up in bonded Darknodes you could have up to $500K of tokens shifted through RenVM at any one specific moment. You could do more than that in daily volume, but at any one moment this is the limit.Beyond this limit, you can still remain secure but you cannot assume that players are going to be acting to maximize their profit. Under this limit, a colluding group of adversaries has no incentive to subvert safety/liveliness properties because the cost to attack roughly outweighs the gain. Beyond this limit, you need to assume that players are behaving out of commitment to the network (not necessarily a bad assumption, but definitely weaker than the maximizing profits assumption).

Q: Why is using ETH as collateral for RenVM a bad idea?
A: Using ETH as collateral in this kind of system (like having to deposit say 20 ETH for a bond) would not make any sense because the collateral value would then fluctuate independently of what kind of value RenVM is providing. The REN token on the other hand directly correlates with the usage of RenVM which makes bonding with REN much more appropriate. DAI as a bond would not work as well because then you can't limit attackers with enough funds to launch as many darknodes as they want until they can attack the network. REN is limited in supply and therefore makes it harder to get enough of it without the price shooting up (making it much more expensive to attack as they would lose their bonds as well).
A major advantage of Ren's specific usage of sMPC is that security can be regulated economically. All value (that's being interopped at least) passing through RenVM has explicit value. The network can self-regulate to ensure an attack is never worth it.

Q: Given the fee model proposal/ceiling, might be a liquidity issue with renBTC. More demand than possible supply?A: I don’t think so. As renBTC is minted, the fees being earned by Darknodes go up, and therefore the value of REN goes up. Imagine that the demand is so great that the amount of renBTC is pushing close to 100% of the limit. This is a very loud and clear message to the Darknodes that they’re going to be earning good fees and that demand is high. Almost by definition, this means REN is worth more.
Profits of the Darknodes, and therefore security of the network, is based solely on the use of the network (this is what you want because your network does not make or break on things outside the systems control). In a system like tBTC there are liquidity issues because you need to convince ETH holders to bond ETH and this is an external problem. Maybe ETH is pumping irrespective of tBTC use and people begin leaving tBTC to sell their ETH. Or, that ETH is dumping, and so tBTC nodes are either liquidated or all their profits are eaten by the fact that they have to be long on ETH (and tBTC holders cannot get their BTC back in this case). Feels real bad man.

Q: I’m still wondering which asset people will choose: tbtc or renBTC? I’m assuming the fact that all tbtc is backed by eth + btc might make some people more comfortable with it.
A: Maybe :) personally I’d rather know that my renBTC can always be turned back into BTC, and that my transactions will always go through. I also think there are many BTC holders that would rather not have to “believe in ETH” as an externality just to maximize use of their BTC.

Q: How does the liquidation mechanism work? Can any party, including non-nodes act as liquidators? There needs to be a price feed for liquidation and to determine the minting fee - where does this price feed come from?
A: RenVM does not have a liquidation mechanism.
Q: I don’t understand how the price feeds for minting fees make sense. You are saying that the inputs for the fee curve depend on the amount of fees derived by the system. This is circular in a sense?
A: By evaluating the REN based on the income you can get from bonding it and working. The only thing that drives REN value is the fact that REN can be bonded to allow work to be done to earn revenue. So any price feed (however you define it) is eventually rooted in the fees earned.

Q: Who’s doing RenVM’s Security Audit?
A: ChainSecurity | https://chainsecurity.com/

Q: Can you explain RenVM’s proposed fee model?
A: The proposed fee model can be found here: https://github.com/renproject/ren/wiki/Safety-and-Liveliness#fees

Q: Can you explain in more detail the difference between "execution" and "powering P2P Network". I think that these functions are somehow overlapping? Can you define in more detail what is "execution" and "powering P2P Network"? You also said that at later stages semi-core might still exist "as a secondary signature on everything (this can mathematically only increase security, because the fully decentralised signature is still needed)". What power will this secondary signature have?
A: By execution we specifically mean signing things with the secret ECDSA keys. The P2P network is how every node communicates with every other node. The semi-core doesn’t have any “special powers”. If it stays, it would literally just be a second signature required (as opposed to the one signature required right now).
This cannot affect safety, because the first signature is still required. Any attack you wanted to do would still have to succeed against the “normal” part of the network. This can affect liveliness, because the semi-core could decide not to sign. However, the semi-core follows the same rules as normal shards. The signature is tolerant to 1/3rd for both safety/liveliness. So, 1/3rd+ would have to decide to not sign.
Members of the semi-core would be there under governance from the rest of our ecosystem. The idea is that members would be chosen for their external value. We’ve discussed in-depth the idea of L<3. But, if RenVM is used in MakerDAO, Compound, dYdX, Kyber, etc. it would be desirable to capture the value of these ecosystems too, not just the value of REN bonded. The semi-core as a second signature is a way to do this.
Imagine if the members for those projects, because those projects want to help secure renBTC, because it’s used in their ecosystems. There is a very strong incentive for them to behave honestly. To attack RenVM you first have to attack the Darknodes “as per usual” (the current design), and then somehow convince 1/3rd of these projects to act dishonestly and collapse their own ecosystems and their own reputations. This is a very difficult thing to do.
Worth reminding: the draft for this proposal isn’t finished. It would be great for everyone to give us their thoughts on GitHub when it is proposed, so we can keep a persistent record.

Q: Which method or equation is used to calculate REN value based on fees? I'm interested in how REN value is calculated as well, to maintain the L < 3 ratio?
A: We haven’t finalized this yet. But, at this stage, the plan is to have a smart contract that is controlled by the Darknodes. We want to wait to see how SubZero and Zero go before committing to a specific formulation, as this will give us a chance to bootstrap the network and field inputs from the Darknodes owners after the earnings they can make have become more apparent.

Vechain in the last 30 Days: Apotheosis, Blockchain X, BMW, University partnership, DApp ecosystem, BitOcean ICO, Carbon banking, Live use cases, Early adopter rewards and more

This post is for those who are new to Cryptocurrency or want to find out more about VeChain. The text "VeChain" has been banned in this subreddit for the last 30 days. For more details about the ban itself, please visit this cryptocurrencymeta post. Changes have been made and official channels of communications have been opened up to prevent this from happening in the future.
All feedback is welcome, and all discussion is encouraged, but please no moon-posting, ridiculous price speculation or baseless FUD. Looking forward to answering any questions you guys have :) VeChain Foundation COO Kevin Feng is holding a Business AMA with Boxmining today, so new information is coming very soon.

TL:DR.

Updates from the last 30 days

It's been a big month for VeChain as they have continued to work and share with the community. Here are the updates from their Official Medium channel and Reddit Rebrand Post

New website - https://www.vechain.org/

It has loads of useful information and a well produced introduction video. I would highly recommend reading through the website to get an idea of the scope of what VeChainThor is trying to accomplish.
"We are controlled by the few, the powerful and the greedy. We should be free. Free to choose, to trade, to create. It is time for a new world, a world founded on safety and security. A world where everything you do creates power, power for all. And you, you will decide the shape of this world. The power to change the future, is in your hands. VeChain." VeChain Introduction Video

What is Blockchain X?

Blockchain X is a global enterprise level public blockchain platform. VeChainThor is referring to their network/protocol as Blockchain X, to differentiate it from Bitcoin (Blockchain 1.0) and Ethereum (Blockchain 2.0 = Blockchain 1.0 + Smart Contracts).

Blockchain X = Blockchain 2.0 + IoT + AI + VET/VeThor = A living digital ecosystem

  • Blockchain = structure - bones, muscle etc (immutable trustworthy network)
  • IoT = senses - touch, vision, taste, smell, sound (collect real world information from RFID/NFC/QR etc.)
  • VET/VeThor = bone marrow/blood - generate blood & circulate (value transfer on the network)
  • AI = brain - information synthesis (automation of network with deep learning)

VeChainThor: the top candidate for enterprise and government level adoption of Blockchain

VeChainThor has an extremely strong development plan geared towards enterprise and government level adoption. If successful in their execution, I see VeChain being the leading cryptoasset comparable to Ethereum in size. The reasons I believe they will succeed are due to their ecosystem development, innovative governance model, robust economic model and strong strategic partnerships. The evidence of their success is snowballing with each new enterprise level partner and client.

DApps & Ecosystem development

The infrastructure layer has adoption in mind at the very core. Governments and enterprises will prioritise safety and security before venturing into blockchain adoption. (Mentioned in the introduction video.) The core DApps, VeVID (Verified identity, KYC/AML), VeVOT (Voting, Governance tool) and VeSCC (Smart Contract Certification, Regulatory compliance) provide the safety and security that governments and enterprises will demand. Blockchain X will have built-in KYC/AML, Governance and Regulation compliance. This sets it apart from other protocols and ICO platforms.

Governance model

The governance model is a balanced mix of decentralisation and centralisation. With problems such as Bitcoin's scaling debate, it appears that a purely decentralised governance structure may be inefficient. VeChain will use a new model of a decentralised system through centralised channels. The final decisions will be made in a decentralised democratic process through VeVOT by stakeholders with voting authority. I believe this model will be more widely adopted as it retains some of the efficient centralised channels that enterprise & government are familiar with, while still giving overall control to the network participants via a democratic voting system.

Economic model

The two-token economic model splits the value in the network into VET and VeThor. VET's primary function is to generate VeThor. VeThor represents the underlying costs of using the VeChainThor blockchain. All smart contract execution and transactions will require payment with VeThor. Through the dynamic rate of VeThor generation, the fiat value of VeThor can be kept relatively stable. For example, if the VeThor price was too high due to an increase in enterprise demand, the VeThor generation rate can be increased, which increases supply, and brings the price back down. The opposite is also true if the VeThor price is too low. The way I see VET is a store of value, a representation of ownership of part of the network and the right to use the network. Whereas VeThor is the perfect medium of exchange and a pure utility token. By using a two-token system, VeThor can have a stable fiat value over a long period of time. A company will be able to calculate how much VeThor will be needed for a consistent fiat value year after year and will be able to budget for this. This is extremely useful for enterprise and government level adoption since it removes the inherent price volatility from a nascent market like crypto.
VeChain also has a Node system, whereby holding VET generates additional rewards. Nodes of different levels will generate up to 200% additional VeThor compared to the base rate. This encourages long term staking in the network and decreases volatility. See the Apotheosis Part II article and X Series Node article for more information. A portion of VET supply will be locked up when nodes activate. Long term VET holders will not sell and downgrade their status. This decreased supply will lead to price increases. Early adopters (Deadline to stake: Before 20th March 2018) will be rewarded in the new X Series Node system. Features include exclusive participation in VeChain ecosystem project whitelists. (Something I'm excited about since I believe there will be a handful of reverse ICOs from traditional enterprise clients)

Technology

VeChain is planning on adding more than 100 additional full-time developers by the end of 2018.
For those interested in the technology of Blockchain X, I would direct you to the Medium AMAs where the VeChain team have provided detailed answers to common questions. Hardware 1, Hardware 2, Software 1 and Software 2 are worth a read.

Strategic partners

The three strategic partners each play a key role in VeChainThor's expansion. PWC has clients which make up 85% of the Fortune 500. DNV-GL is the preferred provider of those Fortune 500 companies for management systems certification services. PWC and DNV-GL will serve to introduce their enterprise clients to VeChain and increase adoption. BitOcean is positioning itself as a Fiat on-ramp for Crypto in Japan through physical ATMs and online exchanges, with approval by Japan's Financial Services Authority. BitOcean also plans to operate in China when regulations are finalised. BitOcean represents a Fiat/VET pairing that may serve to decouple VET/BTC and lead to independence of VET from the whims of BTC price.

Evidence of adoption to date: Existing clients & Investors

VeChain currently has 180 business opportunities in their pipeline for 2018 (compared to 4 use cases in 2016 and 22 in 2017). They have real uses cases and existing clients that range from medium to large enterprises. Revealed clients include Chinese Government Gui'an New Area project, BMW, Groupe Renault, DIG, Kuehne + Nagel, China Unicom, NRCC - State Tobacco, MLILY, Sunshine culture, Hubei Sanxin Cultural Media, Fanghuwang, YIDA future, Madeforgoods and iTaotaoke. Each of these partnerships deserve a detailed post on their own, they are all available on VeChain's Medium page. Taken together, it becomes clear what type of Ecosystem VeChainThor is trying to build.
Jiangsu Printed Electronics and Xiamen Innov Information Technology are technology partners and I suspect will be mass producing the RFID/NFC chips.
Breyer Capital and Fenbushi capital are the two featured investors on VeChain's website. Jim Breyer generally makes some pretty smart investment decisions. His only other crypto investments are Circle and Ethereum.
Bonus news: This week they are presenting with DNV-GL a cold chain supply chain solution at the Global Food Safety Initiative conference 2018. Zoom in and you'll see VeChain Intelligent Control Display System. DNV-GL have also launched their new digital assurance solution, My Story™. Four top Italian wine producers are using My Story™ under supervision of the Italian wine authorities. Twitter and DNVGL link.

China's potential

China is widely known to be anti-cryptocurrency but extremely pro-blockchain. China's "13th Five year plan 2016-2020" focuses on moving up in the value chain by abandoning old heavy industry and building up bases of modern information-intensive infrastructure, with blockchain and Smart Cities being a key technological focus. VeChain has achieved approval from the Government of the People's Republic of China with Gui'an New Area project, multiple mentions on state owned media (CCTV) and deals with state owned enterprises (China Tobacco). China will not fall behind in the international Blockchain race, they will finalise regulations and adopt Blockchain rapidly in the coming years. VeChain appears to be one of the leaders in the field, with their largest office in Shanghai and existing government connections.

Leader in the field

Last but not least, VeChain is leading the field in a number of areas.
  1. Academic research: VeResearch with Michigan State University #1 for supply chain management and another university to be announced
  2. Transparency: quarterly financial reports, regular social media updates, multiple AMAs, response to cryptocurrency ban, directly addressing FUD in official Telegram channels
  3. Corporate responsibility: cryptocurrency disaster recovery plan
  4. Environmental responsibility: Carbon bank initiative with DNV-GL

Skeptics section

In the interests of balanced discussion, I will update this section with skepticism I find in the comments below.
  1. "No whitepaper"
    • VeChain are working on a Whitepaper as part of their Q1 2018 goals. Information normally found in a Whitepaper has been made available through the development plan. I'm actually not too fussed about not having a whitepaper. For me evidence of enterprise adoption is a more useful indicator of how successful VeChainThor could be.
  2. "No official wallet" "No Mainnet"
    • VeChainThor has been operating as a private blockchain since June 2016. Public VeChainThor Blockchain Launch, VeChain Wallet with VeThor Forge Function will be released in Q2 2018 according to the roadmap.
  3. "VeChain are dumping their VET on the open market"
  4. "Can we talk about the fact that the BMW "partnership" is not really a partnership? VEN is allowed to participate into a startup program hosted by BMW. BMW is not a client. http://www.bmwstartupgarage.com/partner " - u/DutchDolt
    • "BMWstartupgarage" has neither been confirmed or denied by BMW or VeChain, it has been spread by a youtuber called "Crypto Gem"
    • Going to the website linked, BMW refers to successful participants as both partners and clients
    • This is still a developing partnership with details under NDA, however the VeChain/BMW link has been confirmed at the VeChain rebranding event and by Sarah VeChain Country Manager
  5. "Vote manipulation" "Shilling" "Brigading" "You're a paid shiller"
    • In the past VeChain Telegram Moderators wilfully participated in brigading, leading to the ban on the word "VeChain" for 30 days in cryptocurrency
    • It is difficult to differentiate manipulated behaviour and organic behaviour on Reddit, the moderators here do an amazing job getting rid of spam and detecting vote manipulation
    • The Official VeChain Foundation has stepped in to help Reddit moderators prevent VeChain vote manipulation
    • Official Telegram Rules: Brigading & Reddit links: We have a new policy regarding Reddit and 'brigading'. No brigading of any kind will be allowed. If you want to post a Reddit link, do so with the "np." prefix added to its URL, for example "np.reddit.com /CryptoCurrency". No spamming for upvotes, as it hurts both of our communities.
    • This is strictly enforced by Telegram moderators and results in a warning then an insta-ban for repeat offenders
    • https://imgur.com/a/sOva9 is being copy-pasted en masse by detractors as evidence of brigading
    • Image shows Boxminig feeling sorry for WTC PR team and a "np" link to a different thread
    • I wish I got paid to shill VeChain, I made this post to share a fundamentally strong crypto with the community _________________________________________________________________________________________

Your Guide to Monero, and Why It Has Great Potential

/////Your Guide to Monero, and Why It Has Great Potential/////

Marketing.
It's a dirty word for most members of the Monero community.
It is also one of the most divisive words in the Monero community. Yet, the lack of marketing is one of the most frustrating things for many newcomers.
This is what makes this an unusual post from a member of the Monero community.
This post is an unabashed and unsolicited analyzation of why I believe Monero to have great potential.
Below I have attempted to outline different reasons why Monero has great potential, beginning with upcoming developments and use cases, to broader economic motives, speculation, and key issues for it to overcome.
I encourage you to discuss and criticise my musings, commenting below if you feel necessary to do so.

///Upcoming Developments///

Bulletproofs - A Reduction in Transaction Sizes and Fees
Since the introduction of Ring Confidential Transactions (Ring CT), transaction amounts have been hidden in Monero, albeit at the cost of increased transaction fees and sizes. In order to mitigate this issue, Bulletproofs will soon be added to reduce both fees and transaction size by 80% to 90%. This is great news for those transacting smaller USD amounts as people commonly complained Monero's fees were too high! Not any longer though! More information can be found here. Bulletproofs are already working on the Monero testnet, and developers were aiming to introduce them in March 2018, however it could be delayed in order to ensure everything is tried and tested.
Multisig
Multisig has recently been merged! Mulitsig, also called multisignature, is the requirement for a transaction to have two or more signatures before it can be executed. Multisig transactions and addresses are indistinguishable from normal transactions and addresses in Monero, and provide more security than single-signature transactions. It is believed this will lead to additional marketplaces and exchanges to supporting Monero.
Kovri
Kovri is an implementation of the Invisible Internet Project (I2P) network. Kovri uses both garlic encryption and garlic routing to create a private, protected overlay-network across the internet. This overlay-network provides users with the ability to effectively hide their geographical location and internet IP address. The good news is Kovri is under heavy development and will be available soon. Unlike other coins' false privacy claims, Kovri is a game changer as it will further elevate Monero as the king of privacy.
Mobile Wallets
There is already a working Android Wallet called Monerujo available in the Google Play Store. X Wallet is an IOS mobile wallet. One of the X Wallet developers recently announced they are very, very close to being listed in the Apple App Store, however are having some issues with getting it approved. The official Monero IOS and Android wallets, along with the MyMonero IOS and Android wallets, are also almost ready to be released, and can be expected very soon.
Hardware Wallets
Hardware wallets are currently being developed and nearing completion. Because Monero is based on the CryptoNote protocol, it means it requires unique development in order to allow hardware wallet integration. The Ledger Nano S will be adding Monero support by the end of Q1 2018. There is a recent update here too. Even better, for the first time ever in cryptocurrency history, the Monero community banded together to fund the development of an exclusive Monero Hardware Wallet, and will be available in Q2 2018, costing only about $20! In addition, the CEO of Trezor has offered a 10BTC bounty to whoever can provide the software to allow Monero integration. Someone can be seen to already be working on that here.
TAILS Operating System Integration
Monero is in the progress of being packaged in order for it to be integrated into TAILS and ready to use upon install. TAILS is the operating system popularised by Edward Snowden and is commonly used by those requiring privacy such as journalists wanting to protect themselves and sources, human-right defenders organizing in repressive contexts, citizens facing national emergencies, domestic violence survivors escaping from their abusers, and consequently, darknet market users.
In the meantime, for those users who wish to use TAILS with Monero, u/Electric_sheep01 has provided Sheep's Noob guide to Monero GUI in Tails 3.2, which is a step-by-step guide with screenshots explaining how to setup Monero in TAILS, and is very easy to follow.
Mandatory Hardforks
Unlike other coins, Monero receives a protocol upgrade every 6 months in March and September. Think of it as a Consensus Protocol Update. Monero's hard forks ensure quality development takes place, while preventing political or ideological issues from hindering progress. When a hardfork occurs, you simply download and use the new daemon version, and your existing wallet files and copy of the blockchain remain compatible. This reddit post provides more information.
Dynamic fees
Many cryptocurrencies have an arbitrary block size limit. Although Monero has a limit, it is adaptive based on the past 100 blocks. Similarly, fees change based on transaction volume. As more transactions are processed on the Monero network, the block size limit slowly increases and the fees slowly decrease. The opposite effect also holds true. This means that the more transactions that take place, the cheaper the fees!
Tail Emission and Inflation
There will be around 18.4 million Monero mined at the end of May 2022. However, tail emission will kick in after that which is 0.6 XMR, so it has no fixed limit. Gundamlancer explains that Monero's "main emission curve will issue about 18.4 million coins to be mined in approximately 8 years. (more precisely 18.132 Million coins by ca. end of May 2022) After that, a constant "tail emission" of 0.6 XMR per 2-minutes block (modified from initially equivalent 0.3 XMR per 1-minute block) will create a sub-1% perpetual inflatio starting with 0.87% yearly inflation around May 2022) to prevent the lack of incentives for miners once a currency is not mineable anymore.
Monero Research Lab
Monero has a group of anonymous/pseudo-anonymous university academics actively researching, developing, and publishing academic papers in order to improve Monero. See here and here. The Monero Research Lab are acquainted with other members of cryptocurrency academic community to ensure when new research or technology is uncovered, it can be reviewed and decided upon whether it would be beneficial to Monero. This ensures Monero will always remain a leading cryptocurrency. A recent end of 2017 update from a MRL researcher can be found here.

///Monero's Technology - Rising Above The Rest///

Monero Has Already Proven Itself To Be Private, Secure, Untraceable, and Trustless
Monero is the only private, untraceable, trustless, secure and fungible cryptocurrency. Bitcoin and other cryptocurrencies are TRACEABLE through the use of blockchain analytics, and has lead to the prosecution of numerous individuals, such as the alleged Alphabay administrator Alexandre Cazes. In the Forfeiture Complaint which detailed the asset seizure of Alexandre Cazes, the anonymity capabilities of Monero were self-demonstrated by the following statement of the officials after the AlphaBay shutdown: "In total, from CAZES' wallets and computer agents took control of approximately $8,800,000 in Bitcoin, Ethereum, Monero and Zcash, broken down as follows: 1,605.0503851 Bitcoin, 8,309.271639 Ethereum, 3,691.98 Zcash, and an unknown amount of Monero".
Privacy CANNOT BE OPTIONAL and must be at a PROTOCOL LEVEL. With Monero, privacy is mandatory, so that everyone gets the benefits of privacy without any transactions standing out as suspicious. This is the reason Darknet Market places are moving to Monero, and will never use Verge, Zcash, Dash, Pivx, Sumo, Spectre, Hush or any other coins that lack good privacy. Peter Todd (who was involved in the Zcash trusted setup ceremony) recently reiterated his concerns of optional privacy after Jeffrey Quesnelle published his recent paper stating 31.5% of Zcash transactions may be traceable, and that only ~1% of the transactions are pure privacy transactions (i.e., z -> z transactions). When the attempted private transactions stand out like a sore thumb there is no privacy, hence why privacy cannot be optional. In addition, in order for a cryptocurrency to truly be private, it must not be controlled by a centralised body, such as a company or organisation, because it opens it up to government control and restrictions. This is no joke, but Zcash is supported by DARPA and the Israeli government!.
Monero provides a stark contrast compared to other supposed privacy coins, in that Monero does not have a rich list! With all other coins, you can view wallet balances on the blockexplorers. You can view Monero's non-existent rich list here to see for yourself.
I will reiterate here that Monero is TRUSTLESS. You don't need to rely on anyone else to protect your privacy, or worry about others colluding to learn more about you. No one can censor your transaction or decide to intervene. Monero is immutable, unlike Zcash, in which the lead developer Zooko publicly tweeted the possibility of providing a backdoor for authorities to trace transactions. To Zcash's demise, Zooko famously tweeted:
" And by the way, I think we can successfully make Zcash too traceable for criminals like WannaCry, but still completely private & fungible. …"
Ethereum's track record of immutability is also poor. Ethereum was supposed to be an immutable blockchain ledger, however after the DAO hack this proved to not be the case. A 2016 article on Saintly Law summarised the problematic nature of Ethereum's leadership and blockchain intervention:
" Many ethereum and blockchain advocates believe that the intervention was the wrong move to make in this situation. Smart contracts are meant to be self-executing, immutable and free from disturbance by organisations and intermediaries. Yet the building block of all smart contracts, the code, is inherently imperfect. This means that the technology is vulnerable to the same malicious hackers that are targeting businesses and governments. It is also clear that the large scale intervention after the DAO hack could not and would not likely be taken in smaller transactions, as they greatly undermine the viability of the cryptocurrency and the technology."
Monero provides Fungibility and Privacy in a Cashless World
As outlined on GetMonero.org, fungibility is the property of a currency whereby two units can be substituted in place of one another. Fungibility means that two units of a currency can be mutually substituted and the substituted currency is equal to another unit of the same size. For example, two $10 bills can be exchanged and they are functionally identical to any other $10 bill in circulation (although $10 bills have unique ID numbers and are therefore not completely fungible). Gold is probably a closer example of true fungibility, where any 1 oz. of gold of the same grade is worth the same as another 1 oz. of gold. Monero is fungible due to the nature of the currency which provides no way to link transactions together nor trace the history of any particular XMR. 1 XMR is functionally identical to any other 1 XMR. Fungibility is an advantage Monero has over Bitcoin and almost every other cryptocurrency, due to the privacy inherent in the Monero blockchain and the permanently traceable nature of the Bitcoin blockchain. With Bitcoin, any BTC can be tracked by anyone back to its creation coinbase transaction. Therefore, if a coin has been used for an illegal purpose in the past, this history will be contained in the blockchain in perpetuity.
A great example of Bitcoin's lack of fungibility was reposted by u/ViolentlyPeaceful:
"Imagine you sell cupcakes and receive Bitcoin as payment. It turns out that someone who owned that Bitcoin before you was involved in criminal activity. Now you are worried that you have become a suspect in a criminal case, because the movement of funds to you is a matter of public record. You are also worried that certain Bitcoins that you thought you owned will be considered ‘tainted’ and that others will refuse to accept them as payment."
This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies. Monero has been built specifically to address the problem of traceability and non-fungibility inherent in other cryptocurrencies. By having completely private transactions Monero is truly fungible and there can be no blacklisting of certain XMR, while at the same time providing all the benefits of a secure, decentralized, permanent blockchain.
The world is moving cashless. Fact. The ramifications of this are enormous as we move into a cashless world in which transactions will be tracked and there is a potential for data to be used by third parties for adverse purposes. While most new cryptocurrency investors speculate upon vaporware ICO tokens in the hope of generating wealth, Monero provides salvation for those in which financial privacy is paramount. Too often people equate Monero's features with criminal endeavors. Privacy is not a crime, and is necessary for good money. Transparency in Monero is possible OFF-CHAIN, which offers greater transparency and flexibility. For example, a Monero user may share their Private View Key with their accountant for tax purposes.
Monero aims to be adopted by more than just those with nefarious use cases. For example, if you lived in an oppressive religious regime and wanted to buy a certain item, using Monero would allow you to exchange value privately and across borders if needed. Another example is that if everybody can see how much cryptocurrency you have in your wallet, then a certain service might decide to charge you more, and bad actors could even use knowledge of your wallet balance to target you for extortion purposes. For example, a Russian cryptocurrency blogger was recently beaten and robbed of $425k. This is why FUNGIBILITY IS ESSENTIAL. To summarise this in a nutshell:
"A lack of fungibility means that when sending or receiving funds, if the other person personally knows you during a transaction, or can get any sort of information on you, or if you provide a residential address for shipping etc. – you could quite potentially have them use this against you for personal gain"

Monero's Humble Origins
Something that still rings true today despite the great influx of money into cryptocurrencies was outlined in Nick Tomaino's early 2016 opinion piece. The author claimed that "one of the most interesting aspects of Monero is that the project has gained traction without a crowd sale pre-launch, without VC funding and any company or well-known investors and without a pre-mine. Like Bitcoin in the early days, Monero has been a purely grassroots movement that was bootstrapped by the creator and adopted organically without any institutional buy-in. The creator and most of the core developers serve the community pseudonymously and the project was launched on a message board (similar to the way Bitcoin was launched on an email newsletter)."
The Organic Growth of the Monero Community
The Monero community over at monero is exponentially growing. You can view the Monero reddit metrics here and see that the Monero subreddit currently gains more than 10,000 (yes, ten thousand!) new subscribers every 10 days! Compare this to most of the other coins out there, and it proves to be one of the only projects with real organic growth. In addition to this, the community subreddits are specifically divided to ensure the main subreddit remains unbiased, tech focused, with no shilling or hype. All trading talk is designated to xmrtrader, and all memes at moonero.
Forum Funding System
While most contributors have gratefully volunteered their time to the project, Monero also has a Forum Funding System in which money is donated by community members to ensure it attracts and retains the brightest minds and most skilled developers. Unlike ICOs and other cryptocurrencies, Monero never had a premine, and does not have a developer tax. If ANYONE requires funding for a Monero related project, then they can simply request funding from the community, and if the community sees it as beneficial, they will donate. Types of projects range from Monero funding for local meet ups, to paying developers for their work.
Monero For Goods, Services, and Market Places
There is a growing number of online goods and services that you can now pay for with Monero. Globee is a service that allows online merchants to accept payments through credit cards and a host of cryptocurrencies, while being settled in Bitcoin, Monero or fiat currency. Merchants can reach a wider variety of customers, while not needing to invest in additional hardware to run cryptocurrency wallets or accept the current instability of the cryptocurrency market. Globee uses all of the open source API's that BitPay does making integrations much easier!
Project Coral Reef is a service which allows you to shop and pay for popular music band products and services using Monero.
Linux, Veracrypt, and a whole array of VPNs now accept Monero.
There is a new Monero only marketplace called Annularis currently being developed which has been created for those who value financial privacy and economic freedom, and there are rumours Open Bazaar is likely to support Monero once Multisig is implemented.
In addition, Monero is also supported by The Living Room of Satoshi so you can pay bills or credit cards directly using Monero.
Monero can be found on a growing number of cryptocurrency exchange services such as Bittrex, Poloniex, Cryptopia, Shapeshift, Changelly, Bitfinex, Kraken, Bisq, Tux, and many others.
For those wishing to purchase Monero anonymously, there are services such as LocalMonero.co and Moneroforcash.com.
With XMR.TO you can pay Bitcoin addresses directly with Monero. There are no other fees than the miner ones. All user records are purged after 48 hours. XMR.TO has also been added as an embedded feature into the Monerujo android wallet.
Coinhive Browser-Based Mining
Unlike Bitcoin, Monero can be mined using CPUs and GPUs. Not only does this encourage decentralisation, it also opens the door to browser based mining. Enter side of stage, Coinhive browser-based mining. As described by Hon Lau on the Symnatec Blog Browser-based mining, as its name suggests, is a method of cryptocurrency mining that happens inside a browser and is implemented using Javascript. Coinhive is marketed as an alternative to browser ad revenue. The motivation behind this is simple: users pay for the content indirectly by coin mining when they visit the site and website owners don't have to bother users with sites laden with ads, trackers, and all the associated paraphern. This is great, provided that the websites are transparent with site visitors and notify users of the mining that will be taking place, or better still, offer users a way to opt in, although this hasn't always been the case thus far.
Skepticism Sunday
The main Monero subreddit has weekly Skepticism Sundays which was created with the purpose of installing "a culture of being scientific, skeptical, and rational". This is used to have open, critical discussions about monero as a technology, it's economics, and so on.

///Speculation///

Major Investors And Crypto Figureheads Are Interested
Ari Paul is the co-founder and CIO of BlockTower Capital. He was previously a portfolio manager for the University of Chicago's $8 billion endowment, and a derivatives market maker and proprietary trader for Susquehanna International Group. Paul was interviewed on CNBC on the 26th of December and when asked what was his favourite coin was, he stated "One that has real fundamental value besides from Bitcoin is Monero" and said it has "very strong engineering". In addition, when he was asked if that was the one used by criminals, he replied "Everything is used by criminals including the US dollar and the Euro". Paul later supported these claims on Twitter, recommending only Bitcoin and Monero as long-term investments.
There are reports that "Roger Ver, earlier known as 'Bitcoin Jesus' for his evangelical support of the Bitcoin during its early years, said his investment in Monero is 'substantial' and his biggest in any virtual currency since Bitcoin.
Charlie Lee, the creator of Litecoin, has publicly stated his appreciation of Monero. In a September 2017 tweet directed to Edward Snowden explaining why Monero is superior to Zcash, Charlie Lee tweeted:
All private transactions, More tested privacy tech, No tax on miners to pay investors, No high inflation... better investment.
John McAfee, arguably cryptocurrency's most controversial character at the moment, has publicly supported Monero numerous times over the last twelve months(before he started shilling ICOs), and has even claimed it will overtake Bitcoin.
Playboy instagram celebrity Dan Bilzerian is a Monero investor, with 15% of his portfolio made up of Monero.
Finally, while he may not be considered a major investor or figurehead, Erik Finman, a young early Bitcoin investor and multimillionaire, recently appeared in a CNBC Crypto video interview, explaining why he isn't entirely sold on Bitcoin anymore, and expresses his interest in Monero, stating:
"Monero is a really good one. Monero is an incredible currency, it's completely private."
There is a common belief that most of the money in cryptocurrency is still chasing the quick pump and dumps, however as the market matures, more money will flow into legitimate projects such as Monero. Monero's organic growth in price is evidence smart money is aware of Monero and gradually filtering in.
The Bitcoin Flaw
A relatively unknown blogger named CryptoIzzy posted three poignant pieces regarding Monero and its place in the world. The Bitcoin Flaw: Monero Rising provides an intellectual comparison of Monero to other cryptocurrencies, and Valuing Cryptocurrencies: An Approach outlines methods of valuing different coins.
CryptoIzzy's most recent blog published only yesterday titled Monero Valuation - Update and Refocus is a highly recommended read. It touches on why Monero is much more than just a coin for the Darknet Markets, and provides a calculated future price of Monero.
CryptoIzzy also published The Power of Money: A Case for Bitcoin, which is an exploration of our monetary system, and the impact decentralised cryptocurrencies such as Bitcoin and Monero will have on the world. In the epilogue the author also provides a positive and detailed future valuation based on empirical evidence. CryptoIzzy predicts Monero to easily progress well into the four figure range.
Monero Has a Relatively Small Marketcap
Recently we have witnessed many newcomers to cryptocurrency neglecting to take into account coins' marketcap and circulating supply, blindly throwing money at coins under $5 with inflated marketcaps and large circulating supplies, and then believing it's possible for them to reach $100 because someone posted about it on Facebook or Reddit.
Compared to other cryptocurrencies, Monero still has a low marketcap, which means there is great potential for the price to multiply. At the time of writing, according to CoinMarketCap, Monero's marketcap is only a little over $5 billion, with a circulating supply of 15.6 million Monero, at a price of $322 per coin.
For this reason, I would argue that this is evidence Monero is grossly undervalued. Just a few billion dollars of new money invested in Monero can cause significant price increases. Monero's marketcap only needs to increase to ~$16 billion and the price will triple to over $1000. If Monero's marketcap simply reached ~$35 billion (just over half of Ripple's $55 billion marketcap), Monero's price will increase 600% to over $2000 per coin.
Another way of looking at this is Monero's marketcap only requires ~$30 billion of new investor money to see the price per Monero reach $2000, while for Ethereum to reach $2000, Ethereum's marketcap requires a whopping ~$100 billion of new investor money.
Technical Analysis
There are numerous Monero technical analysts, however none more eerily on point than the crowd-pleasing Ero23. Ero23's charts and analysis can be found on Trading View. Ero23 gained notoriety for his long-term Bitcoin bull chart published in February, which is still in play today. Head over to his Trading View page to see his chart: Monero's dwindling supply. $10k in 2019 scenario, in which Ero23 predicts Monero to reach $10,000 in 2019. There is also this chart which appears to be freakishly accurate and is tracking along perfectly today.
Coinbase Rumours
Over the past 12 months there have been ongoing rumours that Monero will be one of the next cryptocurrencies to be added to Coinbase. In January 2017, Monero Core team member Riccardo 'Fluffypony' Spagni presented a talk at Coinbase HQ. In addition, in November 2017 GDAX announced the GDAX Digit Asset Framework outlining specific parameters cryptocurrencies must meet in order to be added to the exchange. There is speculation that when Monero has numerous mobile and hardware wallets available, and multisig is working, then it will be added. This would enable public accessibility to Monero to increase dramatically as Coinbase had in excess of 13 million users as of December, and is only going to grow as demand for cryptocurrencies increases. Many users argue that due to KYC/AML regulations, Coinbase will never be able to add Monero, however the Kraken exchange already operates in the US and has XMfiat pairs, so this is unlikely to be the reason Coinbase is yet to implement XMfiat trading.
Monero Is Not an ICO Scam
It is likely most of the ICOs which newcomers invest in, hoping to get rich quick, won't even be in the Top 100 cryptocurrencies next year. A large portion are most likely to be pumps and dumps, and we have already seen numerous instances of ICO exit scams. Once an ICO raises millions of dollars, the developers or CEO of the company have little incentive to bother rolling out their product or service when they can just cash out and leave. The majority of people who create a company to provide a service or product, do so in order to generate wealth. Unless these developers and CEOs are committed and believed in their product or service, it's likely that the funds raised during the ICO will far exceed any revenue generated from real world use cases.
Monero is a Working Currency, Today
Monero is a working currency, here today.
The majority of so called cryptocurrencies that exist today are not true currencies, and do not aim to be. They are a token of exchange. They are like a share in a start-up company hoping to use blockchain technology to succeed in business. A crypto-assest is a more accurate name for coins such as Ethereum, Neo, Cardano, Vechain, etc.
Monero isn't just a vaporware ICO token that promises to provide a blockchain service in the future. It is not a platform for apps. It is not a pump and dump coin.
Monero is the only coin with all the necessary properties to be called true money.
Monero is private internet money.
Some even describe Monero as an online Swiss Bank Account or Bitcoin 2.0, and it is here to continue on from Bitcoin's legacy.
Monero is alleviating the public from the grips of banks, and protests the monetary system forced upon us.
Monero only achieved this because it is the heart and soul, and blood, sweat, and tears of the contributors to this project. Monero supporters are passionate, and Monero has gotten to where it is today thanks to its contributors and users.

///Key Issues for Monero to Overcome///

Scalability
While Bulletproofs are soon to be implemented in order to improve Monero's transaction sizes and fees, scalability is an issue for Monero that is continuously being assessed by Monero's researchers and developers to find the most appropriate solution. Ricardo 'Fluffypony' Spagni recently appeared on CNBC's Crypto Trader, and when asked whether Monero is scalable as it stands today, Spagni stated that presently, Monero's on-chain scaling is horrible and transactions are larger than Bitcoin's (because of Monero's privacy features), so side-chain scaling may be more efficient. Spagni elaborated that the Monero team is, and will always be, looking for solutions to an array of different on-chain and off-chain scaling options, such as developing a Mimblewimble side-chain, exploring the possibility of Lightning Network so atomic swaps can be performed, and Tumblebit.
In a post on the Monero subreddit from roughly a month ago, monero moderator u/dEBRUYNE_1 supports Spagni's statements. dEBRUYNE_1 clarifies the issue of scalability:
"In Bitcoin, the main chain is constrained and fees are ludicrous. This results in users being pushed to second layer stuff (e.g. sidechains, lightning network). Users do not have optionality in Bitcoin. In Monero, the goal is to make the main-chain accessible to everyone by keeping fees reasonable. We want users to have optionality, i.e., let them choose whether they'd like to use the main chain or second layer stuff. We don't want to take that optionality away from them."
When the Spagni CNBC video was recently linked to the Monero subreddit, it was met with lengthy debate and discussion from both users and developers. u/ferretinjapan summarised the issue explaining:
"Monero has all the mechanisms it needs to find the balance between transaction load, and offsetting the costs of miner infrastructure/profits, while making sure the network is useful for users. But like the interviewer said, the question is directed at "right now", and Fluffys right to a certain extent, Monero's transactions are huge, and compromises in blockchain security will help facilitate less burdensome transactional activity in the future. But to compare Monero to Bitcoin's transaction sizes is somewhat silly as Bitcoin is nowhere near as useful as monero, and utility will facilitate infrastructure building that may eventually utterly dwarf Bitcoin. And to equate scaling based on a node being run on a desktop being the only option for what classifies as "scalable" is also an incredibly narrow interpretation of the network being able to scale, or not. Given the extremely narrow definition of scaling people love to (incorrectly) use, I consider that a pretty crap question to put to Fluffy in the first place, but... ¯_(ツ)_/¯"
u/xmrusher also contributed to the discussion, comparing Bitcoin to Monero using this analogous description:
"While John is much heavier than Henry, he's still able to run faster, because, unlike Henry, he didn't chop off his own legs just so the local wheelchair manufacturer can make money. While Morono has much larger transactions then Bitcoin, it still scales better, because, unlike Bitcoin, it hasn't limited itself to a cripplingly tiny blocksize just to allow Blockstream to make money."
Setting up a wallet can still be time consuming
It's time consuming and can be somewhat difficult for new cryptocurrency users to set up their own wallet using the GUI wallet or the Command Line Wallet. In order to strengthen and further decentralize the Monero network, users are encouraged to run a full node for their wallet, however this can be an issue because it can take up to 24-48 hours for some users depending on their hard-drive and internet speeds. To mitigate this issue, users can run a remote node, meaning they can remotely connect their wallet to another node in order to perform transactions, and in the meantime continue to sync the daemon so in the future they can then use their own node.
For users that do run into wallet setup issues, or any other problems for that matter, there is an extremely helpful troubleshooting thread on the Monero subreddit which can be found here. And not only that, unlike some other cryptocurrency subreddits, if you ask a question, there is always a friendly community member who will happily assist you. Monero.how is a fantastic resource too!
Despite still being difficult to use, the user-base and price may increase dramatically once it is easier to use. In addition, others believe that when hardware wallets are available more users will shift to Monero.

///Conclusion///

I actually still feel a little shameful for promoting Monero here, but feel a sense of duty to do so.
Monero is transitioning into an unstoppable altruistic beast. This year offers the implementation of many great developments, accompanied by the likelihood of a dramatic increase in price.
I request you discuss this post, point out any errors I have made, or any information I may have neglected to include. Also, if you believe in the Monero project, I encourage you to join your local Facebook or Reddit cryptocurrency group and spread the word of Monero. You could even link this post there to bring awareness to new cryptocurrency users and investors.
I will leave you with an old on-going joke within the Monero community - Don't buy Monero - unless you have a use case for it of course :-) Just think to yourself though - Do I have a use case for Monero in our unpredictable Huxleyan society? Hint: The answer is ?

- Why BTC is vulnerable for quantum attacks sooner than you would think. -

Blockchain transactions are secured by public-private key cryptography. The keypairs used today will be at risk when quantum computers reach a certain critical level: Quantum computers can at a certain point of development, derive private keys from public keys. See for more sourced info on this subject in part 3. So if a public key can be obtained by an attacker, he can then use a quantum computer to find the private key. And as he has both the public key and the private key, he can control and send the funds to an address he owns.
Just to make sure there will be no misconceptions: When public-private key cryptography such as ECDSA and RSA can be broken by a quantum computer, this will be an issue for all blockchains who don't use quantum resistant cryptography. The reason this article is about BTC is because I take this paper as a reference point: https://arxiv.org/pdf/1710.10377.pdf Here they calculate an estimate when BTC will be at risk while taking the BTC blocktime as the window of opportunity.
The BTC misconception: “Original public keys are not visible until you make a transaction, so BTC is quantum resistant.”
In pretty much every discussion I've read and had on the subject, I notice that people are under the impression that BTC is quantum resistant as long as you use your address only once. BTC uses a hashed version of the public key as a send-to address. So in theory, all funds are registered on the chain on hashed public keys instead of to the full, original public keys, which means that the original public key is (again in theory) not public. Even a quantum computer can't derive the original public key from a hashed public key, therefore there is no risk that a quantum computer can derive the private key from the public key. If you make a transaction, however, the public key of the address you sent your funds from will be registered in full form in the blockchain. So if you were to only send part of your funds, leaving the rest on the old address, your remaining funds would be on a published public key, and therefore vulnerable to quantum attacks. So the workaround would be to transfer the remaining funds, within the same transaction, to a new address. In that way, your funds would be once again registered on the blockchain on a hashed public key instead of a full, original public key.
If you feel lost already because you are not very familiar with the tech behind blockchain, I will try to explain the above in a more familiar way:
You control your funds through your public- private key pair. Your funds are registered on your public key. And you can create transactions, which you need to sign to be valid. You can only create a signature if you have your private key. See it as your e-mail address (public key) and your password (Private key). Many people got your email address, but only you have your password. So the analogy is, that if you got your address and your password, then you can access your mail and send emails (Transactions). If the right quantum computer would be available, people could use that to calculate your password (private key), if they have your email address (public key).
Now, because BTC doesn’t show your full public key anywhere until you make a transaction. That sounds pretty safe. It means that your public key is private until you make a transaction. The only thing related to your public key that is public is the hash of your public key. Here is a short explanation of what a hash is: a hash is an outcome of an equation. Usually one-way hash functions are used, where you can not derive the original input from the output; but every time you use the same hash function on the same original input (For example IFUHE8392ISHF), you will always get the same output (For example G). That way you can have your coins on public key "IFUHE8392ISHF", while on the chain, they are registered on "G".
So your funds are registered on the blockchain on the "Hash" of the public key. The Hash of the public key is also your "email address" in this case. So you give "G" as your address to send BTC to.
As said before: since it is, even for a quantum computer, impossible to derive a public key from the Hash of a public key, your coins are safe for quantum computers as long as the public key is only registered in hashed form. The obvious safe method would be, never to reuse an address, and always make sure that when you make a payment, you send your remaining funds to a fresh new address. (There are wallets that can do this for you.) In theory, this would make BTC quantum resistant, if used correctly. This, however, is not as simple as it seems. Even though the above is correct, there is a way to get to your funds.
Already exposed public keys.
But before we get to that, there is another point that is often overlooked: Not only is the security of your personal BTC is important, but also the security of funds of other users. If others got hacked, the news of the hack itself and the reaction of the market to that news, would influence the marketprice. Or, if a big account like the Satoshi account were to be hacked and dumped, the dump itself, combined with the news of the hack, could be even worse. An individual does not have the control of other people’s actions. So even though one might make sure his public key is only registered in hashed form, others might not do so, or might no know their public key is exposed. There are several reasons why a substantial amount of addresses actually have exposed full public keys:
In total, about 36% of all BTC are on addresses with exposed public keys Of which about 20% is on lost addresses. and here
Hijacking transactions.
But even if you consider the above an acceptable risk, just because you yourself will make sure you never reuse an address, then still, the fact that only the hashed public key is published until you make a transaction is a false sense of security. It only works, if you never make a transaction. Why? Public keys are revealed while making a transaction, so transactions can be hijacked while being made.
Here it is important to understand two things:
1.) How is a transaction sent?
The owner has the private key and the public key and uses that to log into the secured environment, the wallet. This can be online or offline. Once he is in his wallet, he states how much he wants to send and to what address.
When he sends the transaction, it will be broadcasted to the blockchain network. But before the actual transaction will be sent, it is formed into a package, created by the wallet. This happens out of sight of the sender.
That package ends up carrying roughly the following info: the public key to point to the address where the funds will be coming from, the amount that will be transferred, the address the funds will be transferred to (depending on the blockchain this could be the hashed public key, or the original public key of the address the funds will be transferred to). This package also carries the most important thing: a signature, created by the wallet, derived from the private- public key combination. This signature proves to the miners that you are the rightful owner and you can send funds from that public key.
Then this package is sent out of the secure wallet environment to multiple nodes. The nodes don’t need to trust the sender or establish the sender’s "identity”, because the sender proofs he is the rightful owner by adding the signature that corresponds with the public key. And because the transaction is signed and contains no confidential information, private keys, or credentials, it can be publicly broadcast using any underlying network transport that is convenient. As long as the transaction can reach a node that will propagate it into the network, it doesn’t matter how it is transported to the first node.
2.) How is a transaction confirmed/ fulfilled and registered on the blockchain?
After the transaction is sent to the network, it is ready to be processed. The nodes have a bundle of transactions to verify and register on the next block. This is done during a period called the block time. In the case of BTC that is 10 minutes.
If we process the information written above, we will see that there are two moments where you can actually see the public key, while the transaction is not fulfilled and registered on the blockchain yet.
1: during the time the transaction is sent from the sender to the nodes
2: during the time the nodes verify the transaction. (The blocktime)
Hijacks during blocktime
This paper describes how you could hijack a transaction and make a new transaction of your own, using someone else’s address and send his coins to an address you own during moment 2: the time the nodes verify the transaction:
https://arxiv.org/pdf/1710.10377.pdf
"(Unprocessed transactions) After a transaction has been broadcast to the network, but before it is placed on the blockchain it is at risk from a quantum attack. If the secret key can be derived from the broadcast public key before the transaction is placed on the blockchain, then an attacker could use this secret key to broadcast a new transaction from the same address to his own address. If the attacker then ensures that this new transaction is placed on the blockchain first, then he can effectively steal all the bitcoin behind the original address." (Page 8, point 3.)
So this means that BTC obviously is not a quantum secure blockchain. Because as soon as you will touch your funds and use them for payment, or send them to another address, you will have to make a transaction and you risk a quantum attack.
Hijacks pre-blocktime.
The story doesn't end here. The paper doesn't describe the posibility of a pre-blocktime hijack.
So back to the paper: as explained, while making a transaction your public key is exposed for at least the transaction time. This transaction time is 10 minutes where your transaction is being confirmed during the 10 minute block time. That is the period where your public key is visible and where, as described in the paper, a transaction can be hijacked, and by using quantum computers, a forged transaction can be made. So the critical point is determined to be the moment where quantum computers can derive private keys from public keys within 10 minutes. Based on that 10 minute period, they calculate (estimate) how long it will take before QC's start forming a threat to BTC. (“ By our most optimistic estimates, as early as 2027 a quantum computer could exist that can break the elliptic curve signature scheme in less than 10 minutes, the block time used in Bitcoin.“ This is also shown in figure 4 on page 10 and later more in depth calculated in appendix C, where the pessimistic estimate is around 2037.) But you could extend that 10 minutes through network based attacks like DDoS, BGP routing attacks, NSA Quantum Insert, Eclipse attacks, MITM attacks or anything like that. (And I don’t mean you extend the block time by using a network based attack, but you extend the time you have access to the public key before the transaction is confirmed.) Bitcoin would be earlier at risk than calculated in this paper.
Also other Blockchains with way shorter block times imagine themselves safe for a longer period than BTC, but with this extension of the timeframe within which you can derive the private key, they too will be vulnerable way sooner.
Not so long ago an eclipse attack demonstrated it could have done the trick. and here Causing the blockchain to work over max capacity, means the transactions will be waiting to be added to a block for a longer time. This time needs to be added on the blocktime, expanding the period one would have time to derive the private key from the public key.
That seems to be fixed now, but it shows there are always new attacks possible and when the incentive is right (Like a few billion $ kind of right) these could be specifically designed for certain blockchains.
MITM attacks
An MITM attack could find the public key in the first moment the public key is exposed. (During the time the transaction is sent from the sender to the nodes) So these transactions that are sent to the network, contain public keys that you could intercept. So that means that if you intercept transactions (and with that the private keys) and simultaneously delay their arrival to the blockchain network, you create extra time to derive the private key from the public key using a quantum computer. When you done that, you send a transaction of your own before the original transaction has arrived and is confirmed and send funds from that stolen address to an address of your choosing. The result would be that you have an extra 10, 20, 30 minutes (or however long you can delay the original transactions), to derive the public key. This can be done without ever needing to mess with a blockchain network, because the attack happens outside the network. Therefore, slower quantum computers form a threat. Meaning that earlier models of quantum computers can form a threat than they assume now.
When MITM attacks and hijacking transactions will form a threat to BTC, other blockchains will be vulnerable to the same attacks, especially MITM attacks. There are ways to prevent hijacking after arrival at the nodes. I will elaborate on that in the next article. At this point of time, the pub key would be useless to an attacker due to the fact there is no quantum computer available now. Once a quantum computer of the right size is available, it becomes a problem. For quantum resistant blockchains this is differetn. MITM attacks and hijacking is useless to quantum resistant blockchains like QRL and Mochimo because these projects use quantum resistant keys.

We're quite wealthy, earning hundreds of BTC per year in profit from our systematic cyber-extortion. GCHQ coined that term for us. You can read their advisory about this organisation.
Q: Hi, thedarkoverlord, Have you considered that information may well be used crash the monetary system you hope to be compensated in? A: Fantastic question, mate. We're not concerned about that as we receive our payments only in internet money like Bitcoin. The monetary crash will be your problem. We always advise our clients to diversify and acquire different convertible currencies.
Q: Explain attack vector that lead to initial shell. Web based? Misconfigired service? Well known exploit? A: Nice try, Mandiant.
Q: How? You stated that your intent was to sell it to the highest bidder. That just means that it will get buried. A: We're financially motivated. We're not motivated by saving the planet.
Q: Waiting for overlords dead man switch A: We have several layers of 'dead man's switches' deployed. This is why the entire archive we'd plan to release is freely downloadable now. We're sitting on our high entropy master encryption keys that can be released through even a failure of the organisation.
Q: The thing is, I (and few others) are willing to pay. Provided that OP understands at least basics how such trades are executed. A: We're highly reputable, having sold hundreds of BTC worth of intellectual property, R&D, databases, and more. Our official contact details are in our office Press Release. Please contact us using PGP. We'll happily conform to your requirements to substantiate our loot.
Q: if you DO get paid then we can assume the world's not save because you'd not release them right? A: That's correct. We're not here to save the world. We're here to get paid internet money. We're not motivated by ego or charity, only money.
Q: Hey thedarkoverlord, give us something for free you poofters. A: We already have. Pay attention, fag.
For everyone speaking about the hack of a global insurer, you should understand how sophisticated litigation works. We're sitting on SSI and SCI from TSA, FBI, FAA, USDOJ, and others. Refer to our official PR for more information.
Q: Thoughts on Cicada 3301 and WikiLeaks? particularly who is behind Cicada? A: We don't speculate on other organisations. We focus on ourselves.
Q: Do you have a timeline you can disclose for releasing each layer? A: There is a timeline, but we can't share details about that.
Q: Your group could have chosen to privately auction this info to the same exact bidders you will likely get through these public antics. That makes me question your timing. Why disrupt our system of things and way of life now ( assuming your I do is as world changing as you state)? Why now? A: Tis the season.
Q: I don't give a shit what he wants I'll kick in 20 bucks for anything that peaks my interest one single doc to prove it's not a nothing burger with no strings attached I've been sitting on btc since 50 btc blocks. A: Ff you'd like to be the first person to purchase a single file or two from us, you're welcome to. We'd happily sell you something right now. Our Twitter has our e-mail on it. Get in contact, mate.
Q: what would anyone who is selling world shattering documents for millions of dollars try selling them on 4chan? A: We're not selling anything on 4chan. We're working SEO right now. Google 'thedarkoverlord' and see for yourself. It's driving a tremendous amount of traffic to our content. This is all calculated and pre-arranged.
Q: Fuck yeah based hackerman. I read the release, make those fuckers pay for breaking the deal. They should pay extra just for being so stupid to let you find anything in their network in the first place. Too easy probably, IT people are lazy as fuck. Get paid. A: We've probably hacked your company too.
Q: I'd be willing to chip in with others to see it if I was sure it would be world shaking info. Not something the average person would change the TV when it came up on the news. On a scale of 1-10 how system breaking is the info? A: You're the smart one here, asking the right questions. We'd say it's a 7.5, all things considered. Snowden may have been a 5.5, maybe a 6. More people care about 911 than USA spying. Now, our next release about UFOs, yeah, that's a 10 mate, but it's going to wait until we're done here. If you'd like to buy 911 documents from us, read the answers above.
Anyone can see ample proof on our official PR and our official Twitter @tdo_h4ck3rs. This is quiet real. We'd like to top Edward Snowden. Everyone saying they're coming for us: we know. GCHQ has published advisories about us and the Billings Gazette news publisher leaked the fact that the CIA and NSA event attempted to locate us last year in October after we closed down 50.000 students and 36 schools in an entire region of Montana for 7 days. This is readily available news.
Q: Actually appears legit. On a scale of 1 to 10, how likely do you think it is that your leak could cause a former-sitting president to get lynched? Also, hope your DMS shoots to a Blockchian. A: We'd rather not say, for fear of his safety.
We'll be sharing a few new screencaps momentarily, to stir the pot a bit.
Q: why are you doing ransom instead of exploiting this information for insider trading A: We're experts in systematic cyber-extortion, according to GCHQ. We do what we're best at.
Q: Do you have anything really damaging on Hillary or Obama? A: We're unwilling to answer this question.
Q: Holy kek, FreeBSD is one of the most insecure OS, no joke. A: We utilise Windows Embedded.
Q: That's a bit of a lame answer. Why pick a risky strategy like cyber extortion, when you can stay under the radar, and do insider trading from a beach in Asia? A: We don't discuss out TTPs in public.
Q: So given your financial motivation, is it safe to assume you’re “group” is more anarchy than order? That is to say, are you looking to shift power,take power, or destroy power? A: We're not interested in power, only internet money.
Q: Their answer here will actually clue in their degree of technical competency. I'd add - justify why it will reach this price. A: We haven't shared a price, at all. Depending on what a buyer would like, we adjust our offer.
Q: Iron Mountain is a military base. Why is a WTC Insurer shredding documents on it? A: Great question. We'll direct you to ur official PR which details it. We'll quote the issue for you below:
"When major incidents like the WTC 911 incident happen, part of the litigation must involve SSI (Sensitive Security Information) and SCI (Special Compartment Information) from the likes of the FBI, CIA, TSA, FAA, DOD, and others being introduced into evidence, but of course this can't become public, for fear of compromising a nation's security, so they temporarily release these materials to the solicitor firms involved in the litigation with the strict demand they're destroyed after their use and that remain highly protected and confidential to only be used behind closed doors. However, humans aren't perfect and many of these documents don't become destroyed, and when thedarkoverlord comes along hacking all these solicitor firms, investment banks, and global insurers, we stumble upon the juiciest secrets a government has to offer."
Q: Hey do you take hack requests? I have a couple of bitcoins... A: Visit our official Twitter @tdo_h4ck3rs where our contact details are readily available. We operate on a strict protocol and often times require bonding.
Q: why leak on new years eve A: Because it forces about a dozen Fortune 500 companies in the UK and USA to build damage control and COA plans on their New Years holiday, robbing them of any pleasure and bringing in their new year at a new low.
Q: if i purchase the doc's, whats stopping me uploading it everywhere? will you guys get annoyed? A: Once we're paid, they're yours. You do as we you wish. We couldn't care any less.
Q: yeah has there been any strange shit happening that makes you think they're on to you or that you've being targetted already? A: Other than them telling victims to pay us because it's the best move to save their arses, we sleep like babies.
Q: Likes,kind of a career ending big heist, don't you think? A: We already live like the ending of a great heist movie, on warm beaches with loads of internet money. We're quite happy.
Q: Why do you care about their pleasure or them starting new year at all time low, thought this was all just business? A: It's all business. Psychologically, they're most vulnerable when this process is used and it resutls in higher success rates for us.
Q: Apparently the guy they caught was in Serbia. A: A complete random stranger.
Q: The question about crypto was good, do you have any predictions about BTC next year and do you think it's still the best currency to invest in? A: We predict we'll earn even more BTC. As our clients are paying us while we have them bent over a barrel, we always advise them to buy up for their personal portfolios.
Q: Do you have a deadman set up A: We do.

I coded an app to solve the problem of FOMO when daytrading

Hey reddit coiner, I’m Chris.
To solve FOMO problem, my app calculated social trend data like: No. of new Twitter followers of a coin within 24h’, ‘% of new Twitter followers per day compared to the last 30 days average’, etc.

For example, two week ago, Bitcoin surge a lot, but in the first day and even a full week before, there were no increase to the number of new Reddit subscribers a day, the number of new posts and online users didn't change compared to the month before. The amount of mentions about Bitcoin on Twitter even reduced compared to earlier months, so this price surge is probably just a bull trap.

Therefore, I sold my BTC a week ago when i saw a pinbar combined with a double top pattern, so I got away from the dump to 3500. I saw similar pattern in other coin token pairs I trade. I do think the connection between crypto social and price is pretty close aside from news and TAs.

That aside, I also included small features like notification when there’s a price surge in cryptocurrency within 60 minutes (or a pump and dump as you call it), or when a coin is listed or delisted.
This is link for android: https://play.google.com/store/apps/details?id=com.cointrendtracker
And for dude who use iphone: https://itunes.apple.com/app/apple-store/id1443987253?mt=8

Important thing to note:
- If you don't want to login, just choose " Stay incognito" option at bottom
- This crappy indie app won’t require any permission from your phone, so you don’t have to worry about the safety of your private keys.

I build it by myself with the help of some friends (i’m Major in Computer Programming). I know it just an unknown app, and you may find it so silly but i’d love to hear what you guys honestly think. I love coding useful tools for crypto trader so if you have any idea, but you aren’t able to make it, you can tell me about it via my email and I’ll try to make it a reality if I am able to.
My email is: [[email protected]](mailto:[email protected])
Thanks for reading until here. Bless y’all

P/s: Sorry if you guys see my post too often. It’s my first time coding and I wanna spread my app around and Reddit is all I got :’( Hope im not bothering anyone and thanks for your feedbacks! Really!
And, I made this app trying to solve a painful issue, and the task itself is very fun for me. Though if you guys wanna buy me a coffee or something i’d gladly accept. If you guys like, I could credit your usernames or real names in a special place in the next versions of the app. You can find my wallet in comment.

Some food for thought for new crypto investors

I'm in the crypto game since end of May and I have invested in several cryptos, made a lot of newbie mistakes, made some money but mainly learned a LOT about investment strategies.
Crypto currencies investment is very specific and trading techniques don't really apply here. If you don't prepare yourself and educate yourself before investing, you will probably lose money or end up bagholding for a while.
It takes time to do your own research, understand the mechanics to be able to invest wisely and optimize your profit.
Here is a compilation of the rules I learned and I'm forcing myself to follow to avoid the common pitfalls.
Feel free to comment and add more rules if you have any. I will edit this post if I can recall some more later on and based on your feedbacks.
This is by far the only rule that you should have in mind anytime you invest money in something. And this especially applies to crypto which is more volatile than anything you could have invested in so far.
Don't ever take a loan or lend money to buy crypto, don't invest all your life savings or money you need for your daily life.
Before investing in any coin, take enough time to thoroughly read as much as you can from existing documentation, whitepapers, posts, blogs,... Understanding what you are investing your money in is absolutely key to success.
Don't trust anyone, be critical and don't take any news, rumors or investing advice at face value. Subreddits, blogs, YouTube,.. are full of people shilling, fuding, and lying about cryptos to manipulate the price for their profit. Cross-check reading, facts checking and asking questions are your best friends and will help you debunk fake information.
It's good to believe in a project but if you get too emotional it may blind you to hodl when it's time to sell and cut your losses, or to buy at ATH.
Right now, most of the crypto projects are over speculated and overvalued. Most of them will fail and their token price will probably fall down to 0. Some projects are more mature and are less risky than others. Usually their token is already priced in so they are good for long term investment, because the price will likely raise more steadily.
But most people will want to invest in more risky coins to get more reward. "Fortune goes to the bold" they say. If you go that way, you will invest in projects with merely a working product, and most of the time only a single whitepaper. Whatever extraordinary and awesome the promises these projects hold, the rise of the price will only be driven by speculation at this point so don't get too fanatic about it. You definitely will want to get out if you feel that the fundamentals have changed so set your objectives and exit strategy before investing.
You will experience FOMO many times and will be tempted to buy during a pump and you will probably end up buying at ATH. Pumps are usually followed by a dump or correction. Sometimes the dip is temporary if you get lucky, but most of the times it's not. So you can end up bagholding until it pumps again.
Buying at the right time is the most difficult thing to do in crypto and timing the market is almost impossible.
You will see a lot of people providing trading technical analysis and trying to predict the next price movement. Sometimes these predictions will be realized but most of the times they won't.
Crypto markets are overly manipulated and it's difficult to predict prices when whales and bots are acting behind the scenes.
If you believe in the future of a coin on the rise, remember that "the best time to buy it was yesterday and the second best time is now". If the price goes x10 or more in a year or 2, it won't matter if you bought it at a price 20% higher back then.
However, if you can, be sure to always have some funds available to buy the dip. It will help you accumulate more hence making more profit when price will rise.
It will most of the time be better to buy regularly a smaller but constant amount rather than one big chunk at once. This is a proven investment strategy that will pay off in the long term.
Similarly, you can also average buy during a price dip to avoid missing the bottom that can be directly followed by a recovery.
Plan your strategy, set your selling price/ target profit % before buying anything and stick to it.
You will often be tempted to keep holding your coin during a pump rally, beecause heck, why should you sell when your coin keeps going up?
First, it won't last forever and every pump is always followed by a price correction.
Second, if you don't take some profit at some point, you take the risk to get no profit at all if you miss the ATH and end up stuck in the dump with a price below your buy price.
It's better to sell a chunk of your holdings to secure some profit and keep the other chunk to stay in the game for longer term
Always set stop limit sell to avoid being caught in a dump and forced bagholding until price recovers. Recovery can take days, or months or it can never happen...
Depending on your strategy, and your aversion to risk, it is often wiser to not invest in only one single crypto unless you only want to hold btc.
Choose coins that fill different niches and serve real purpose by solving a genuine problem. Follow rule #1 to make your choices.
Hodl = hold (you will learn about this meme soon enough when you have read enough sub posts)
If you are not day trading, your strategy will consist of either buying and holding coins for long term, or buying undervalued coins to sell part or all of them after price has gained xx %.
So the question is: is it a better strategy to just hodl coins and wait or being an active trader and leverage the fluctuations between altcoins and btc or ETH to optimize your profit?
You will get different answers to this question from people depending of their own experience and belief.
When I started investing, I had convictions and faith in some coins that I was planning to hold for very long term. For some of them, it still apply as of today and I'm still holding them because I have enough confidence about their future. But from a pure investment and profit perspective, having too much faith in a coin is not that good of a strategy.
From my experience, in the end the only coin to really hold is BTC, at least for now. As you will experience yourself, altcoins and btc prices are correlated but fluctuations of both depend of many factors.
Usually, when money flows to btc, and btc price rallies, altcoins prices are falling because people are selling their altcoins to buy BTC. This is especially true when a fork is planned few weeks ahead for instance because people wants to get free coins hence free money. It's basic human psychology
Several times I've been caught by these btc rallies and ended up bagholding altcoins because of people switching to btc. That's why it's important to regularly take your profit and convert back to btc, so you don't end up missing out btc price rally. Numerous times I've been experiencing this, and regreted not having converted back my stake to btc earlier because in the end it was more profitable to hold btc rather than my altcoins.
Of course, what I have described above is not always what is happening. You might see altcoins rally up while btc price is rallying as well. Staying well informed and up to date about the coins you are watching is important to be able to make good decisions and catch the pumps that can be more profitable than just holding btc.
One thing to consider also is that although BTC can be seen as outdated or obsolete features-wise for some, currently you can't workaround it if you want to buy crypto and basically make money. There are not many cryptos besides BTC, LTC or ETH that you can use to buy other cryptos. On most exchanges these are the only ones paired to altcoins so you need to trade for them first or buy them with your fiat money before being able to buy altcoins. Also when you'll want to cash out you will need to convert your altcoins to btc first and then sell your BTC. This is not the case on all exchanges and more cryptos pairs are being added over time.
But until more altcoins become as compulsory and compelling as BTC, you need to stay focus on one single objective when you trade or hold tokens: increase your BTC stake. The fiat price of altcoins are for most of them calculated from their price against BTC. To be clearer, If BTC price rallies up and your altcoin price stays the same, you are basically losing money, or to be more exact, your investment would be better if it was in BTC instead of your altcoin.
You know, when I started investing I was very confident about the future of other blockchains and cryptocurrencies that would eventually take over BTC that I was considering obsolete at that time. But after some time, I understood that despite all its flaws, all the hard forks drama, BTC is still there, and is very resilient to all the FUD and attacks towards it.
I'm still convinced that there are many cryptos that do things better than BTC, that PoW is not ideal, etc... But here's the catch: crypto space is large enough to have competing blockchains that fill a gap or a niche left by others. In this perspective, I can still see BTC relevant as a store of value. I don't think it will stay that way for ever, and maybe direct bitcoin competitors will take over in the future, but right now, tbh, BTC has never been stronger. Just look at the price...
Crypto exchanges are not secure despite all the security measures put in place. Hackers know there is something to be stolen so they will do everything they can to find exploits to get those precious tokens stored in those exchanges. Many hacks have been successfully made so far (Mt. Gox, Bitfinex, e-btc,..) and a lot of people have lost their tokens. I'm not even counting all the scams and fake websites that exploit users carelessness to stole their private keys and tokens. Nowadays, some exchanges security has been improved to avoid these massive hacks, and tokens staked are usually stored in cold storage not connected to the network. Only tokens traded are stored temporarily on hot wallets.
Another thing to consider is that when you store your tokens on an exchange, you don't hold the private keys of your wallets. The only thing you have is an IOU from the exchange when you will want to trade or withdraw your tokens. In case of a hack and tokens theft, you have no guarantee that the exchange will compensate you.
Some exchanges are more reputable than others but most of them at least have enforced users to enable 2FA authentication, which is a bare minimum. I STRONGLY advise to use only TOTP-based or similar application for 2FA and NEVER use 2FA with SMS. Especially if you live in the US. It is far too easy to get your personal information from social networks and impersonate you to make a phone operator migrate your number to the phone of a hacker.
Many people will say to never leave anything on exchange. I think this mainly apply if you want to hold for long term and never trade. Unless you transfer large sums and don't care about transfer time and withdrawal fees, it can get quite painful to go back and forth from your wallets to the exchanges, especially if you hold many different cryptos. So if you plan to trade from time to time, you can leave enough on the exchanges to make these trades and keep your main holdings safely on your hardware, software or paper wallets. When you're done trading for a while, transfer back your tokens to your wallet. Also, it could be wiser to split your tokens and store them across different exchanges so you split the risk of losing everything in case of a hack.
Note for newbies: when you start trading the first time and buy your first tokens for a modest sum, it's probably safer to let your tokens on the exchange until you get enough knowledge about wallets and know what you are doing. I witnessed numerous times people losing their private keys or password hence their tokens, because they forgot where they were stored or their hard-drive crashed, or they couldn't remember their password or lost their private key seeds.
You need to be very careful with your wallet so you need to learn how it works, the address, the fees, how to do multiple backups of your keys, etc.... Until then, and if you don't mind losing the tokens and money in case of a hack, then it's probably safer to keep them in a reliable exchange. You can be your own enemy sometimes...
When you will be experienced enough about wallets, the most reliable and secure option is to store your tokens in a hardware wallet such as Ledger or Trezor.
Edit1: added another Rule about exchanges and wallet. Than you for your feedbacks!!
Edit2: added a more detailed opinion about btc and why it is important to hold it, at least for now.

340 BTC

October, 2011 was when I first heard about Bitcoin. A friend excitedly told me about it, that the price had crashed, that it could be 'mined', and that it could be purchased on exchanges. He didn't own any, but he found it interesting, and so did I. I was instantly interested in acquiring some coins. That the price had 'crashed' meant a buying opportunity, and I further saw it as evidence that the system was somehow free, and had a life of its own. I did not purchase any right away, regretfully, since the coins were about $3 each. I did do some initial research, calculating mining profitability, and looking into the process for buying coins on MtGox. I also read about the thefts and hacks. I found it intuitive these incidents were matters of endpoint-security, and not reflective of a systemic weakness. Yet I would have much to learn if I was to avoid becoming a victim. I continued to casually follow Bitcoin developments, and occasionally checked the price.
Eight months later I came across a Timothy B. Lee article in Forbes that detailed the Bitcoin Richlist. It was my catalyst. It was time for a technical deep dive, time to understand what gave people the confidence to entrust millions of dollars of value to the system. Of everything I read that day, it wasn't the proof-of-work that seemed revolutionary, but simply the fact that a lost private key meant the coins would be irrecoverable. That signified Bitcoin put true and total control of money into the hands of users, and for that it was different and worthwhile. I decided to invest. All that was left was working out the mechanics of the transaction. And security. I was determined to not fall victim to a hack. An offline, paper wallet seemed like the easy choice. The price was in the $6 - $7 range.
My first purchase went though MoneyGram and Coinapult, with MtGox as my receiving wallet. I put in $150, and got out $130 worth of coins. The price had surged in the few days since I decided to buy, to slightly under $10 per coin. I transferred the coins off of MtGox and onto my paper wallet, and it all felt very real! I wanted to buy more, and settled on CoinFloor to avoid the hefty fees I paid the first time. CoinFloor also allowed for instant fiat funding via a deposit at a bank teller window. Depositing $900 directly into a bank account was not without risk, but CoinFloor came through and the money was credited within 5 minutes. It all went flawlessly, and soon with my 100 coins spread out over a few different paper wallets, I could rest easy, without fear of a hack.
Edit - I meant BitFloor, not CoinFloor
I occasionally checked the price, tested out Satoshi Dice, and read a little more on the technical underpinnings, but other than that, I mostly forgot about my Bitcoin investment for the next 6 months. Then, in early 2013, I read about a few seed rounds in Bitcoin startups, and I saw pictures of a Bitcoin booth at the CES is Las Vegas. Somehow that booth, with the Bitcoin logo, made it all seem even more legitimate. The price had climbed into the $14 - $15 range, and I wanted more coin. CoinFloor had been hacked and was out of commission. This time I would use the Dwolla to MtGox method of funding. I found myself seriously regretting not having done Gox's verification the previous summer, as the price quickly climbed while I waited. When my verification finally cleared, the price had shot up to $19, and I transferred in several thousand dollars and bought another ~150 coins. Over the next few months I kept buying until the price crossed $100 per coin. In total, I had put in about $10,000 for 340 coins. I worked part-time, with an annual income of about $25,000, so that $10,000 felt substantial.
The rise to $266 was exhilarating, as was the following surge to $1242. I mostly held, but sometimes tried to time the market with a small position (always 10% of holdings or less). I sold some coins the first time Bitcoin passed the $400 mark to recoup my initial investment, and I arbitraged when it was profitable. I lost a then-painful amount of fiat on MtGox, but not any coins. I held tight during the long bear market, with absolute confidence that the price would find a non-zero bottom, and it would only be up from there. The ecosystem was growing, the technology was maturing, and investment money was pouring in, and yet the price continued to decline. I would have loved to buy more, but doing so would have been truly irresponsible from a diversification perspective.
I have largely stayed away alt-coins, but I did mine-and-dump those I found annoying, and mined and held the one that I found interesting - Ethereum. I reluctantly pushed some BTC into Ethereum early this year, which turned out to be a good move. In total, over the past 5 years, I have returned about 200x on my initial investment, in the current form of about 250 BTC, about 700 ETH and approximately $300k of other liquid assets. The result is almost identical to a pure buy-and-hold from the beginning, but I felt the need to hedge as valuations changed over time. I feel no pressure to sell more coins, though I probably would convert a few in the $20k-$40k range, prices which I have long seen as likely, if not inevitable.
I am in my early 30's. Ask Me Anything! Though I might only have time to answer a few…
