BCH vs. LTC, Roger Ver vs. Charlie Lee. Who are they? What do they stand for?

I just started typing this but I can already tell it's going to be super long. Sorry about that, but if you really do care about the answer to this question I am about to give you my point of view. DISCLAIMER: I hold no BCH, and do hold some amount of LTC. I'm not a whale mind you, just an average investor. However, like all things internet you should take even that with a grain of salt. I will never tell you that my viewpoint is the best or that I have any credentials that matter in this space.
Back in 2013 I decided to get into Bitcoin mining (waaaay late to that game). I knew ASICS were coming out and I had a BFL miner ordered. It never showed up and I never made my millions mining, but in the meanwhile I had 4 GPU rigs running 2xRadeon 7950's. What to do with them? I started mining Litecoin. If I was a little more proactive I would have mined whatever the most profitable GPU coin was at the time and converted it straight into BTC. However, being the lazy complacent son of a bitch I am, I decided to leave them mining LTC.
I read everything about LTC and though to myself “I am glad there's a coin that copies Bitcoin but runs on its own network.” I thought that the mere fact LTC is a completely reduntant system (and at the time the ONLY one imo) protected by its own hash algorithm already made it extremely valuable.
I frequented the subreddit under a different user name, and for the most part I actually stopped paying attention to Bitcoin. I thought: “Litecoin is extremely undervalued, and I'm not going to put anything back into BTC until I feel like the price ratio reflects that value”. Thus, I have almost no Bitcoin and most of my disposable income went straight into LTC. Mind you, I had to sell for medical reasons a couple times and various other things happened (like stupidly trying to day trade using reefer and red wine chart analysis).
Charlie Lee was always this awkward tech figure that stood in the background of the subreddit. He hadn't learned how to shoot himself in the foot with Twitter back then, and mostly just posted technical updates and questions to the community. He wasn't Litecoin Jesus. In fact, most of us didn't really give two shits about what he said beyond getting excited when he was working on something we thought was inherently valuable.
Anyway, it was clear to everyone at the time that he was a dev, not a PR guy. We never flocked around him for answers and he never claimed to have them. He still doesn't. That's what made his opinion on matters valuable, you didn't get that used-car-saleman vibe like all he was interested in was pitching his product.
Enter Roger Ver. I knew almost nothing about this guy until a couple years ago, and I still don't know a lot because quite frankly after googling him and reading all the shit he has done I really don't want to. The guy is super aggressive, hostile, and volatile. I saw videos of him freaking out at people for not calling his altcoin the real Bitcoin, reading a statement verbatim from Mt. Gox while pretending it was his own, etc etc. Yet somehow, he has garnered a huge following. I guess this shouldn't surprise me, since I see the coin he backs as a product he is pitching rather than something that emerged naturally. It sickens me.
I know it's preaching to the choir on this subreddit, but I feel like I had to say something since it's honestly starting to worry me how much political sway Roger Ver is starting to have. I see people all over the subreddit claiming that Charlie Lee is just like Roger Ver, which is pretty fucked up IMO.
Tl;dr: Charlie Lee = Dev, Roger Ver = Used car salesman
BCH itself has nothing inherently wrong with it, it is not a crime merely to exist. It has value from the people who give it value, just like any other crypto. However, I am of the opinion that most of that value is derived from strong marketing rather than a strong coin (from a development OR a real use standpoint).

Back to the Future: 2014 Bitcoin increase, market Crash, and GPUs flood the market.

Image a world, where Bitcoin hits a new ATH of 1,000 USD! A new coin emerged, Litecoin. Using a new Algorithm called SCRYPT which makes GPU mining profitable and a thing again!
The story starts in January 2014. AMD Just released it's newest GPU, the R9 290X in late Oct. this thing a monster of a GPU, extremely powerful! A GPU mining crazy has just hit the internet and waves of Tech people are making mining farms to mine Crypto. AMD GPU's are priced at premiums with 290's/290x's OOS or for sale upwards of $700, $200 over MSRP. Everyone is gulping up used AMD GPUs. Ebay is awash with GPUs selling over MRSP even used ones!
I was there, I started out mining Litecoin to, I had 3 Rigs I slapped together in crate boxes. Mixature of 7970/7950/7850's and a single a 4 GPU R9 290x rig (over 1400w!!!) using AMD AM3+ Motherboards and CPU's running Windows 8. I even near the end had a 750ti Rig, the new Maxwell, efficiently mining SRCYPT. I'm glad i lived in WA at the time The electric bill wasn't bad at all maybe 200-300 a month. I lived in Ellensburg getting that sweet Wind farm Electric rate. I Remember this time as I struggling to learn mining, overclockings for mining, and rig stability. In the short period I did this February 2014 to May of 2014 I made 48 Litecoins. This was a fun period for me because I loved messing with the hardware and GPUs even made decent profits from selling used hardware because it became such a premium then. In the end I quit mining and sold all my hard around May/June. Then moved back to CA to live with my mom to help support her after she lost her job and couldn't find work. I sold off my entire small operation. In the end the Market crashed, MT GOX was hacked millions of Bitcoin lost, and SCRYPT ASICs were released. I stopped paying much attention to the crypto-sphere and just HODLed the small Bitcoin that I had traded from the Litecoin I earned. Bitcoin dropped down to $200 by the end of that year.
All in all I just want everyone to take in the fact that this exact, I repeat EXACT, thing has happened before in the long forgotten past of 2014. Yet everyone is making it out like its some crazy big deal? every crypto is still at high comparing to previous years, GPUs have declined in price because mining has died down, and ASICs are coming out for almost every Algo.
To those of you still mining, keep on my brother! If I had kept mining, or kept on eye on the crypto sphere rather than walking away like most are right now, I could mined Etherum back in the early days of 2015 and now could of been extremely well off. Now, that im in it again and this time with more foresight and readiness. I'm here to stay through this rough times. hopefully to come out to see the otherside. I Only started(again) in june 2017 so I was late for this "gold rush" but mark my words the massive "Gold rush" for crypto has yet to come...
Some Articles back then
TLDR: History repeats itself.

[Discussion] My own personal guide to used hardware alternatives.

Hi there. My name is Jeff. I've been building systems for the better part of 15 years and try my best to contribute here actively. After being involved in this little community for a few years now, I'm noticing a serious lack of discussion about buying used components, and I feel like it's time to shed a little light on the subject for those looking to build on a (seriously) tight budget.
As Linus said in his scrapyard wars video, buying new on $300 isn't practical, and if you posed the challenge to him on a random day, buying used is almost certainly the path he'd choose. As someone who's been "scrapyarding" as a hobby for the better part of 10 years, I figured I'd take some time to share some of what I've learned for the modern audience.
Let's begin with a simple rundown of modern "budget" choices, and I'll tell you what I'd do instead.
The G3258 and Athlon 860k are the sub-$100 CPUs of choice, and both work just fine. I have built with both in the past, and each carries their own set of advantages.
Used Alternatives: You can go in a couple of directions here; if you happen to have an LGA 1366 motherboard lying around, you can get an i7 920 or better for under $50, and they still hold up reasonably well. Being that LGA 1366 boards are not typically cheap when purchased used, my favourite option is the Phenom II x4 Black Edition series, each of which compare favourably to modern budget options, and will even overclock on some incredibly dated, dirt cheap AM2+ boards. In my experience, eBay prices on these get a little too high for my taste, but I've been able to nab several on Kijiji locally in Toronto for under $50 as well.
The R7 260x and GTX 750 ti are often cited as budget options for most builders, with the latter serving a very specific role in systems where power draw might be a concern. While there exists no option that can complete with the low consumption of the 750 ti (or even the single 6-pin connector goodness of the 260x), its performance can easily be matched (and exceeded) for less money.
Used Alternatives: The bitcoin mining craze from a few years back led to the Radeon 7950 and 7970 being blacklisted on the used market, and I think the fears about burned-out cards are a little overblown. Here in Toronto, you can easily grab a 7950 for the price of a 260x, but I don't pay anywhere near that for my builds. At most, a Windforce will cost me $125, as where I recently picked up some non-boost edition PowerColor versions for a mere $83 each (bought 3 for $250).
EDIT: Forgot to mention something important - avoid the reference 7950 and 7970. They were employed to a far greater degree in mining rigs because of their rear-only exhaust, and if you see a bunch of them from the same seller listed at once, they're likely old mining cards. Only pick them up if they're incredibly cheap.
Want to go even cheaper? The Radeon 6950 (with the shader unlock, preferably) or even the 6970 will rival the performance of the 260x, and shouldn't cost Canadians more than $50-$60. I personally have 2 in my possession right now, and have gone through at least a dozen in the last 6 months.
In general, one should always avoid Nvidia when buying used, because they are far too popular and overvalued for their performance as they age. I still see GTX 660s selling for $150, which is absolutely absurd.
Motherboards on the used market are weird, and this can largely be attributed to the fact that they're hard to transport and don't handle well over time. As such, people don't really sell boards on their own that often, and you'll likely have more luck finding a combo of some kind (or even a ready-to-go tin-can with no graphics card) for less per part than you will finding a given board on its own.
Used Alternatives: The boards I'd recommend depend entirely on the CPU you've chosen. Being that I'm a fan of the Phenom II x4 series, AM2+ boards are going to be dirt cheap, but DDR2 RAM is actually fucking expensive, so you'd likely be better off going with AM3. I've even seen some used AM3+ boards (The 970 ASRock Extreme3, in particular) for as low as $40, so it wouldn't hurt to look.
On the Intel side, you're actually at a significant disadvantage. Much like Nvidia cards, Intel boards (and CPUs) actually retain their value and don't often come cheap. For me, LGA 1156 is the price/performance sweet spot, granted I can find an i7 8XX to go with it. Even still, they're going to run you a fair bit more than an AMD board, and likely aren't worth it by comparison.
Ram is ram. DDR2 is pricy as fuck due to an obvious market shortage of the stuff, so the AM2+ board option might not be best by comparison. DDR3 ram, however, is ubiquitous, and I always die a little inside when people building on a "budget" choose to buy new at all. If I'm being honest, I can get DDR3 ram from e-waste recycling companies for as low as $10 per 4GB stick, at 1333MHz, and not once have I ever had a bad stick of the stuff. Even for people going the route of the G3258 (which only supports 1333MHz), this is the clear winner.
Is value RAM ugly as sin? Sure it is. It is just as good as that fancy Ripjaws shit you've got in your current build? You betcha.
Hard Drives are actually a tricky game, as they are the single most volatile component in any budget build, easily succumbing to wear and tear from age and daily use. As such (and some might find this hard to believe) I actively avoid HDDs when building value systems for people and opt for cheap SSDs instead. As always, check the date on a drive if you're really insistent on buying one, and considering how cheap a WD blue is new, don't pull the trigger on one unless it's for less than $30/TB.
SSDs are obviously (akin to RAM) highly resilient and are nearly guaranteed to work when purchased used. The average SSD pulled from an old laptop or an office off-lease desktop, will have no more than 100GB of writes on it, which leaves 99% of its life for you to exploit. While there exists no specific recommendation for which brand to buy, just be sure you're getting a relatively good drive with SATA III capability. 120/128GB variants of these sorts should cost you no more than $50 in my native Canada, and I've even gotten lucky on some larger sizes too. Recently I picked up 4 256GB Samsung 840 Pros for $75 each (I came), just days after I bought a Crucial MX100 of the same size for $85.
Monitors are fun to buy, because the recent shifts in display technology have rendered a lot of recent-but-obsolete models nearly valueless. For example, remember when 16:10 was a thing? I actually still like 1680x1050 monitors, but the rest of the world seems to disagree, so I've been able to pick up 23" variants for as little as $40. Being that the slightly lower resolution actually eases the strain on your VRAM a bit, it's a nice fit for a lot of budget cards that might not have a full 2GB available, like some variants of the 6950. 1600x900 monitors are often just as cheap and come with the same inherent benefit of being obsolete despite being almost as good as its bigger 1080p cousin.
Keyboards and Mice
If you're on a budget, we can't even have this discussion. As much as I like mechanical keyboards and high-precision gaming mice, people building used $300 systems aren't going to allot any of their budget buying them. That said, wired USB keyboards and mice are virtually free (search your local goodwill or value village for some), and if you have to pay money, buy a wireless combo for $20 new from some little shit store in a suburb somewhere.
Cases on their own sell for about half of their original retail price, give or take based on the condition. I normally just get them as a part of a tin-can bundle and make use of them if they aren't too dirty, but when building for someone else, I'd often just prefer to buy a new budget case in the $40 range.
I saved this topic for last, because it's by far the most difficult category to master. First off, you really need to do your research and understand how PSUs work before delving into these guys, as the cost associated is almost entirely dependent on how resilient the underlying platform has been proven to be. Generally speaking, reading reviews on JonnyGuru and HardOCP is a great start, but none of them account for units that are several years old.
As a general rule of thumb, I use the EVGA 500W W1 as a reference point, and build my value tree around that. In other words, if a new EVGA 500W (a passable, proven budget unit) is cheaper than a used 500W variant of a better brand, why would I bother buying used? Sure, that 520W Seasonic S12II puts the EVGA to shame in terms of voltage regulation and ripple suppression, but can I really make the same claims of a unit that's 5 years into its life? Wouldn't I just be safer buying new? These are all factors you have to consider.
For me, the threshold lies around 50% in terms of cost savings vs. risk. In other words, if you can find a used quality unit for less than half the price of the cheapest quality unit available at a given time, buy it.
Anyhow I think that covers everything. And as a closing note, remember to be safe. Meet potential sellers (and buyers) in public, well-lit places, and try your best to avoid entering someone's home without some protections in place. Also, the more info you get about the person (address, phone number, etc) the less likely it is that a person will be trying to scam you. People who purposely conceal their identity do so for a reason.
Also, feel free to ask me anything about my own experiences buying and selling used. I've been doing it as a hobby for a long, long time and have sold many value builds to people who can't otherwise afford PCs. I'm happy to impart any wisdom I might've gained over the years.
Edit: CPU Coolers! Forgot those. Air coolers are a safe bet. They're slabs of copper and aluminum with fans strapped to them. Buy with confidence, and seek one out for $10-$15 if you plan to overclock. AIO water cooling is not so safe. Those things are typically only good for 2-3 years, and you have no idea how much longer a pump has before it gives. Budget builders likely aren't water-cooling anyhow, right?
Edit 2: Just to be clear, when I said I'd been doing this for a long time, I should clarify that a) I once owned a game store and sold systems out of there and b) I currently resell systems out of my house to raise money for charity builds. I really don't want people to get the impression I'm trying to sell anything.

New people please read this. [upvote for visibility please]

I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can.
Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here.
If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier.
Mining. What is it?
Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section.
Mining Hardware
While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much.
Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it.
So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy.
Should I mine?
Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats

Estimated Hashrate (with GPU overclocking) : 1900 KH/s
Hardware Fundamentals
CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with.
RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory.
HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats)
GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like.
PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption.
MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less.
PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied.
When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info.
Mining Software
Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head)
Mining Pools
Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself.
How do I connect to a pool?
Most pools will give you a tutorial on how to but the basics are as follows:
  • Signup for a pool
  • Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
  • Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As> (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
  • Double click on (or whatever you named it) and have fun mining.
Mining Profitability
This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine:
Hardware cost: The cost of your physical hardware to run this whole operation.
Power: Measured in $/KwH is also known as the operating cost.
Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon.
Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously.
Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones.
I like this one cause it is simple. The fields are self explanatory. Try it.
I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account.
Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it!

So we launched a seed store that accepts bitcoin...

We decided to launch a medical marijuana seed site that accepts crypto currencies.
That might not sound like the hugest deal unless you are on the hunt for the finest cannabis seeds but we decided to go one step further than most. We don't just accept crypto currencies but we are entirely built inside the crypto ecosystem.
We have decided to try and run without any fiat input. I have 4 radeon 7950s that have been mining for the past 8 months beneath my desk and they are our budget. We bought our hosting, we bought our domain, we bought our SSL certificate all with bitcoins mined beneath our desk (well we mine on a multipool and convert to BTC). Now our advertising budget is what we have left from mining/what we will mine. We have also managed to convince our biggest distributor to accept bitcoin, so our payments stay as crypto. We did not use bitpay or coinbase or any other site which immediately converts to crypto.
I made this post not just as an advertisement for our site but also to share our attempt to break free of fiat and be one of the first to go full Crypto. We are in this for the long haul.
If you have any questions please ask away
PS. my business partner bought the .com domain with his credit card so we redirect to the until time comes that I can renew in crypto

A disgruntled opinion/rant regarding Bitcoin/Litecoin/etc. mining and the enthusiast GPU market.

Back in June of 2012, I very eagerly built my rig with a single Radeon 7950 in anticipation of crossfiring it down the road with a 7970. Now that time has come, and in my efforts to procure what I had anticipated to be quite the bargain, I am absolutely flabbergasted by what I discovered.
There's not a decent Radeon 7xxx in sight, and the 7970s that I could find are going for upwards of $400 USD! This is simply unacceptable for a two-year-old card, and even more unacceptable when considering that these very cards were (according to this guide) retailing for $269.99 this past October! That is nearly a 50% price increase in just two months at the very end of the card's life, and just after the universal price drop to all 7xxx units complimenting Nvidias launch of their GTX700s.
I hope I'm not being oblivious/naive here - and please correct me if I am - but I have NEVER seen that happen before with ANY consumer product (that is being replaced by a new revision). Of course I know the economic rules of supply & demand: There are lots of people who want these few cards, so AMD can afford to boost the price on them. However, this is pretty unreasonable considering AMDs focus on the new R9 chips, which are the new supply.
The perpetrator here is the growing trend of Bitcoin mining. The computing power and efficiency of AMDs GCN architecture is extremely good at mining for this "magic internet money." A growing amount of people are noticing this, and thus demand for AMDs chips has blown up like crazy. It's even become a goddamn selling point in advertisements.
I understand that the processing power of these cards can be very well harnessed for coin mining, and that's fine. However, for those of us enthusiasts that enjoy using our video cards to push pixels, I anticipate this trend to continue putting a strain on the market and our wallets.
TL;DR: I'm butthurt about last-gen AMD GPU prices being unreasonably high, and get mad (within reason).
*edit: AMD is not boosting prices, retailers are. Thanks to Shrederrr for clarifying.
**edit: To all the people suggesting that I sell my 7950 on the secondhand market, thanks; that is a good idea. Honestly the solution didn't cross my mind at the time of making this post - I was still reeling from the unbelievable prices and frustrated that I wasn't able to follow my planned upgrade path. This unprecedented Bitcoin/Litecoin phenomenon caught me by surprise and it saddens me somewhat to see these enthusiast GPUs being used in such a menial, greedy fashion. It's like seeing a Ferrari V12 powering a backup generator for a t-shirt factory. Sure it's being put to good use, but it's just...not right.

Not So Brief History of my Radeon HD7950 ASUS Direct CU II

Sexy Beast Pic 1:
Sexy Beast Pic 2:
ASUS HD7950 Direct CU II. This card mined 1.5-3 BTC Bitcoin for me. Started with Bitcoin, then mined Litecoin in the early days of Litecoin GPU mining. Had 2 X ASUS HD7950s running 24/7/365 at the time. Each did about 3 BTC each total, and then switched full time to LTC Litecoin. This card was also used for CS gaming, 3D rendering, real time graphics, some video editing, and yes, yes more mining! Still RUNNING today! AMD FTW!
After some test mining Litecoin for a month, I quickly built 2 more Radeon GPU rigs to mine LTC. Total 3 rigs 12 cards. Blazin! Then in Dec 2013 this setup mined millions of Dogecoin in a few days shortly after launch,... I remember raking in over 300-500K DOGE / day at full throttle. We setup our own Doge Pool, and DOGE miners were chatting on IRC: The Excitement was REAL!
This fun SUCH DOGE WOW time was cut short by a massive ice storm that knocked out the power for a week. So no more DOGE. When I got back online diff was up and production down to 30K per day or less, but DOGE price skyrocketed so I sold DOGE for a good profit.
I remember donating DOGE to send the Jamaican Bobsleigh Team to the 2014 Winter Olympics, and they made it to Sochi! What a time to be alive! I was a DOGE Millionaire by then... Such Card, Much DOGE! WOW!
Shortly after that, around March 2014 the second HD7950 blew some caps and need to be sent to ASUS for service. ASUS promptly replaced the card under 3 year warranty and shipped a replacement in two weeks. Mining frenzy continued with FeatherCoin and PotCoin. DGB Digibyte was the next chapter! ;]
In summer 2015 I decided to part with one of them. Sold on Kijiji to a local fellow gamer that had his video card blow up, and didn't have enough $ to buy a new one. Gave him a deal. The guy was so happy, it was like Xmas for him. I knew that this ASUS 7950 will have a great home. So I said Good Bye to engine #2.
When this card is retired I will box it for display. Been through so much with it, still my number 1 engine. When something is this good, you keep it in the Fam'. Still works great. Thank you ASUS & AMD for making kick ass products! Over & Out! Peace! ;]

New user (Hasrate 0.0kh)

Hey there! I just recently heard about crypto currency a few hours ago and I thought I might try to be a part of it! So this is my first day trying it (and my first day ever using Redit)
So far I watch a few tutorials on what bitcoins are, how to set up a wallet, get a pool, ect. And after syncing the dogecoin wallet, i loaded my .bat and it's running with nut2pool
but for some reason it's been stuck at 0.0 Hashrate for a while. Every now and then it would go up to 69KH , but after 10 seconds go right down to 0.0 again.
My setup: Intel I5 /// 12GB Ram /// Radeon HD 7950 Using cgminer-3.7.2 for windows 7 , and I have a 30mb time warner connection.
Code: cgminer --scrypt -o stratum+tcp:// -u -p -o stratum+tcp:// -u rikkusguardian.shadow -p flamesofel3
Am I doing something wrong?

[Upgrade] Most cost efficient upgrades for a £250-500 budget? Unsure :(

Hi guys. I'm in a bit of a dilemma here, as my PC is still performing fairly well, but the FPS is low in the more modern games and as I play competitively it's important for me to keep a high FPS. I am not sure whether it's better to 'wait it out' and spend £1000 later on, or upgrade a few key components now. Any advice?
Here are my specs currently:
CPU: Intel Core i5-4690k
GPU: AMD Radeon HD 7950/r9 280
RAM: 8GB Kingson DDR3 SDRAM (2x 4GB sticks)
I'm guessing upgrading the CPU or GPU is the next step, but I have heard things about GPUs being overpriced due to bitcoin mining at the moment, and I'm not sure out of those two which is likely to be more of a bottleneck. Any advice guys?
I'm also unsure whether it's better to spend, say, £500 on a new GPU, or £200 on a CPU and £300 on a gpu.

xpost from /r/bitcoin "So we launched a seed store that accepts bitcoin..."

We decided to launch a medical marijuana seed site that accepts crypto currencies.
That might not sound like the hugest deal unless you are on the hunt for the finest cannabis seeds but we decided to go one step further than most. We don't just accept crypto currencies but we are entirely built inside the crypto ecosystem.
We have decided to try and run without any fiat input. I have 4 radeon 7950s that have been mining for the past 8 months beneath my desk and they are our budget. We bought our hosting, we bought our domain, we bought our SSL certificate all with bitcoins mined beneath our desk (well we mine on a multipool and convert to BTC). Now our advertising budget is what we have left from mining/what we will mine. We have also managed to convince our biggest distributor to accept bitcoin, so our payments stay as crypto. We did not use bitpay or coinbase or any other site which immediately converts to crypto.
I made this post not just as an advertisement for our site but also to share our attempt to break free of fiat and be one of the first to go full Crypto. We are in this for the long haul.
If you have any questions please ask away
PS. my business partner bought the .com domain with his credit card so we redirect to the until time comes that I can renew in crypto

[Build Complete] FrankenPC: gaming, bitcoin mining, HTPC

This is an all-purpose build that I put together slowly over the past year. It started out as just an HTPC, but ballooned into a gaming and bitcoin mining system. What's not listed in pcpartpicker is an additional HD 6850 connected by a PCIe x1 riser for bitcoin mining. The total hashrate of the system is 780 MH/s. Mining has been going full-on for about 4 months now and about a 1/3 of the cost of the current system has been paid for. It probably won't continue at this rate if difficulty goes way up with the asics coming out, but a 1/3 of the cost already is still a lot.
The i5-3450 and 7950 are a great combination for gaming. FPS on ultra detail on BF3 is 40-60 on a 1080p HDTV with AA/MSAA at their lowest settings.

Linux headless setup

I'm setting up a mining rig using 3-7950's, and have ran into a little bit of a road block. I've seen a few guides using xubuntu 12.10, but none with xubuntu 13.04.
darth_bunny's guide
cryptobadger's guide
gentoo (bitcoin)
I've tried the first 2 ways on fresh images, but for some reason X never starts...
aticonfig --adapter=0 --od-getclocks ERROR - X needs to be running to perform AMD Overdrive(TM) commands 
Following the darth_bunny's guide way I built to 13.04 instead of 12.10
./ --buildpkg Ubuntu/raring 
On a side note, whenever I plug the ATI cards in, video (connected to onboard), does not output. I'm guessing this is because the ATI cards are primary? It didn't bother me as I ssh in anyway.
I also have some missing lib's when trying to run cgminer, but that is something to worry about later.
Has anyone solved this on 13.04, or should I just downgrade to 12.10?
