Updated FAQs for newcomers
TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party. Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this? Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?" Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here. Now, why are these changes so large? A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010. In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon. In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips. In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race. ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty. The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months. Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
I read that you can mine with a CPU/GPU, should I do so?
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase. And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
I get free electricity and I have existing hardware, should I still mine?
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
Should I buy an ASIC machine?
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
You are assuming your pre-order will arrive on time. (I do not think any first batch pre-order from any manufacturer has arrived on time).
All pre-orders are sold out for 1 Dec.
You are assuming your chips will run at 450Gh/sec minimum but many miners here will tell you their chips have been under performing.
Electricity cost have not been taken into account.
Shipping cost and time has not been taking into account.
Import Tax or VAT has not been taken into account.
Risk of downtime due to DOA or warranties has not been taken into account.
You are assuming the difficulty increase will be a constant 35% which is very unlikely because Cointerra with a team that has worked on some of the world’s highest performance CPUs, GPUs and chipsets for NVIDIA, Intel, Samsung, Qualcomm and Nortel has pre-sold an absurd amount of hash rate. Difficulty increase of 45% or more (which we have seen when a small player, KnC shipped their 1st batch) will be repeated commonly. This is only 1 company, imagine what the rest will come out with. I have failed repeatedly and so have many in estimating future hashrate. You wont be able to do better.
Even if you earn some profit, it will be < 15% and will probably be not worth your risk or your trouble. I can buy and hold XBT with no risk of losing them.
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case. The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
I understand I probably won't earn any money, I just want to do this for fun/hobby...
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
I want something with more omph and still do not mind losing money
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
Who are the manufacturers?
You can check out the manufacturers and their products below along with a calculator here. If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice. Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee. However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
Which pool should I use?
I actually do not use any of the pools recommended to the left because I think they lack features. My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap. Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me. BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised. All of them pay out transaction fees.
GPUs will make a comeback to mining, and in doing so, will destroy the security of the Bitcoin network
The reason why Bitcoin is relatively secure right now is because the cost to mine is extraordinarily expensive. Why is it so expensive? Not because of the cost of the silicon, or even really the cost to manufacture, but because the only use of an ASIC is for mining SHA-256 cryptocurrencies such as Bitcoin. When people pay up to $15,000 for an ASIC miner, they're paying for all the time and effort that went into it. But consider this: What if mining machines become multi-purpose? In particular, what if GPUs return to the fore as competitive mining machines? Now I know what you're thinking; you're thinking 'You fool, GPUs will never come close to the efficiency of an ASIC'. But the thing is, they don't need to be. They only need to be cheap, since the purchase cost of an ASIC greatly outweighs its electricity cost. A 'CoinTerra AIRE' ASIC slated for release in March this year will cost $2499 and do 4500 GH/s. Now taking into account a number of factors like electricity cost and rate of value depreciation, I'd estimate that for a $200 GPU to be competative, it needs to do about 225GH/s - an improvement of 375x on current hardware. Impossible you say? Well, the hash rate of nVidia GPUs has improved by ~70-80x in just a few years, without any intentional focus towards Bitcoin: 5.66 MH/s 8600GT to ~414 MH/s GTX 960. The nVidia GTX 780ti is a top of the line card currently priced at $440 and it does 0.5 GH/s, yet an Ati 280X which costs just half the price does at least 0.7 GH/s. Ati cards have always displayed better performance in mining, but why? I'm no expert on the technical details, so I'll only say what can be deduced and is relevant: GPU designs can be altered to increase efficiency/performance when it comes to Bitcoin mining - this is a proven fact from the Ati/nVidia difference! So far, these chipset makers have no doubt been focused on improving gaming performance. But what if they realize that there are many people who will buy more of their GPUs if they have the added benefit of good mining performance, as in 2011? Surely it wouldn't be too difficult or expensive to rearrange things a bit or slap a few things on - If a bunch of amateurs can create ASICs, how difficult could it be for a multi-billion dollar company to improve the hash rate of their GPUs at minimal extra end cost to the consumer? Or what if gaming just naturally tends more towards GPUs having better hash rates? When this happens, Bitcoin will have a security crisis on its hands. There are millions of people with mid or high level graphics cards. In Q1 2014, AMD and NVidia sold a combined 14 million add-in boards. But let's be conservative - let's use the publically available Steam data, which says that yesterday there were a peak 8.3 million concurrent users online. Steam's hardware survey says about 65% of these are not mid or high level cards, so 0.35 x 8.3 mil = 2,905,000 people with decent AMD or nVidia cards who are conscious users (i.e. not office workers) at a certain time of day. For those 2.905 million gamers to launch a concerted and sucessful 51% attack on the network, their GPUs would only need to do on average 57.14 GH/s. If $200 GPUs were to be doing 225 GH/s, the entire number of ASICs throughout the world would be no match! If you want a 'tl;dr' then go listen to Fenton or Shrem egg you on to buy or something - stay in your little dreamland while the price falls like a rock
Some Bitcoin users might wonder why there is a huge disparity between the mining output of a CPU versus a GPU. First, just to clarify, the CPU, or central processing unit, is the part of the computer that performs the will of the software loaded on the computer.It's the main executive for the entire machine. Bitcoin mining can be highly profitable, but it requires power-hungry hardware and a deep understanding of the principles that drive blockchain technology. In order to mine Bitcoin, you’ll need specialized bitcoin mining hardware called application-specific integrated circuit devices, or ASICs. There are many different ASICs on the market today. These devices have evolved through a highly ... It is important to consider the value of GPUs since when you start mining Bitcoin or Ethereum, you will not be generating large amounts of cryptocurrencies. Therefore, you should try to mitigate your initial costs as much as possible to maximize your profits and start recovering your initial investment as soon as possible. Best Mining Graphics Card 2020.
