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

When it comes to Bitcoin (BTC) mining, the major questions on people’s minds are “how profitable is Bitcoin mining” and “how long would it take to mine one Bitcoin?” To answer these questions, we need to take an in-depth look at the current state of the Bitcoin mining industry — and how it has changed — over the last several years.
Bitcoin mining is, essentially, the process of participating in Bitcoin’s underlying security mechanism — known as proof-of-work — to help secure the Bitcoin blockchain. In return, participants receive compensation in bitcoins (BTC).
When you participate in Bitcoin mining, you are essentially searching for blocks by crunching complex cryptographic challenges using your mining hardware. Once a block is discovered, new transactions are recorded and verified within the block and the block discoverer receives the block rewards — currently set at 12.5 BTC — as well as the transactions fees for the transactions included within the block.
Once the maximum supply of 21 million Bitcoins has been mined, no further Bitcoins will ever come into existence. This property makes Bitcoin deflationary, something which many argue will inevitably increase the value of each Bitcoin unit as it becomes more scarce due to increased global adoption.
The limited supply of Bitcoin is also one of the reasons why Bitcoin mining has become so popular. In previous years, Bitcoin mining proved to be a lucrative investment option — netting miners with several fold returns on their investment with relatively little effort.

Mining Hardware
The mining hardware you choose will mostly depend on your circumstances — in terms of budget, location and electricity costs. Since the amount of hashing power you can dedicate to the mining process is directly correlated with how much Bitcoin you will mine per day, it is wise to ensure your hardware is still competitive in 2019.
Bitcoin uses SHA256 as its mining algorithm. Because of this, only hardware compatible with this algorithm can be used to mine Bitcoin. Although it is technically possible to mine Bitcoin on your current computer hardware — using your CPU or GPU — this will almost certainly not generate a positive return on your investment and you may end up damaging your device.
The most cost-effective way to mine Bitcoin in 2019 is using application-specific integrated circuit (ASIC) mining hardware. These are specially-designed machines that offer much higher performance per watt than typical computers and have been an absolutely essential purchase for anybody looking to get into Bitcoin mining since the first Avalon ASICs were shipped in 2013.
When it comes to selecting Bitcoin mining hardware, there are several main parameters to consider — though the importance of each of these may vary based on personal circumstances and budget.
Performance per Watt
When it comes to Bitcoin mining, performance per watt is a measure of how many gigahashes per watt a machine is capable of and is, hence, a simple measure of its efficiency. Since electricity costs are likely to be one of the largest expenses when mining Bitcoin, it is usually a good idea to ensure that you are getting good performance per watt out of your hardware.
Ideally, your mining hardware would be highly efficient, allowing it to mine Bitcoin with lower energy requirements — though this will need to be balanced with acquisition costs, as often the most efficient hardware is also the most expensive. This means it may take longer to see a return on investment.
In countries with cheap electricity, performance per watt is often less of a concern than acquisition costs and price-performance ratio. In most countries, operating outdated mining hardware is typically cost prohibitive, as energy costs outweigh the income generated by the mining equipment.
However, this may not be the case for those operating in countries with extremely cheap electricity — such as Kuwait and Venezuela — as even older equipment can still be profitable. Similarly, miners with a free energy surplus, such as from wind or solar electric generators, can benefit from the minimal gains offered by still running outdated hardware.
Longevity
The lifetime of mining hardware also plays a critical role in determining how profitable your mining venture will be. It’s always a good idea to do whatever possible to ensure it runs as smoothly as possible.
Since mining equipment tends to run at a full (or almost full) load for extended periods, they also tend to break down and fail more frequently than most electronics — which can seriously damage your profitability. Equipment failure is even more common when purchasing second-hand equipment. Since warranty claims are often challenging, it can often take a long time to receive a warranty replacement.
Price-Performance Ratio
In many cases, one of the major criteria used to select mining hardware is the price-performance ratio — a measure of how much performance a machine outputs per unit price. In the case of cryptocurrency mining hardware, this is commonly expressed as gigahashes per dollar or GH/$.
Under ideal circumstances, the mining hardware would have a high price-performance ratio, ensuring you get a lot of bang for your buck. However, this must also be considered in combination with the acquisition costs and the expected lifetime of the machine — since the absolute most powerful machines are not always the cheapest or the most energy efficient.
Acquisition Costs
Acquisition costs are almost always the biggest barrier to entry for most Bitcoin miners since most top-end mining hardware costs several thousand dollars. This problem is further compounded by the fact that many hardware manufacturers offer discounts for bulk purchases, allowing those with deeper pockets to achieve a better price-performance ratio.
Acquisition costs include all the costs involved in purchasing any mining equipment, including hardware costs, shipping costs, import duties, and any further costs. For example, many ASIC miners do not include a power supply — which can be another considerable expense, since the 1,000W+ power supplies usually required tend to cost several hundred dollars alone.
Ensuring your equipment runs smoothly can also add in additional costs, such as cooling and maintenance expenses. In addition, some miners may want to invest in uninterruptible power supplies to ensure their hardware keeps running — even if the power fails temporarily.

Current Generation Hardware
One of the most recent additions to the Bitcoin mining hardware market is the Ebang Ebit E11++, which was released in October 2018. Using a 10nm fabrication process for its processors, the Ebit E11++ is able to achieve one of the highest hash rates on the market at 44TH/s.
In terms of efficiency, the Ebang Ebit E11++ is arguably the best on the market, offering 44TH/s of hash rate while drawing just 1,980W of power, offering 22.2GH/W performance. However, as of writing, the Ebang Ebit E11++ is out of stock until March 31, 2019 — while its price of $2,024 (excluding shipping) may make it prohibitively expensive for those first getting involved with Bitcoin mining.
Another popular choice is the ASICminer 8 Nano, a machine released in October 2018 that offers 44TH/s for $3,900 excluding shipping. The ASICminer 8 Nano draws 2,100W of power, giving it an efficiency of almost 21GH/W — slightly lower than the Ebit E11++ while costing almost double the price. However, unlike the E11++, the 8 Nano is actually in stock and available to purchase.
ASICminer also offers the 8 Nano Pro, a machine launched in mid-2018 that offers 80 TH/s of hash rate for $9,500 (excluding shipping). However, unlike the Ebit E11++ and 8 Nano, the minimum order quantity for the 8 Nano Pro is curiously set at five, meaning you will need to lay out a minimum of $47,500 in order to actually get your hands on one (or five).
While the 8 Nano Pro doesn’t offer the same performance per watt as the Ebit E11+ or AICMiner 8 Nano, it is one of the quieter miners on this list, making it more suitable for a home or office environment. That being said, the ASICminer 8 Nano Pro is easily the most expensive miner per TH on this list — costing a whopping $118.75/TH, compared to the $46/TH offered by the E11++ and $88.64 offered by the 8 Nano.
The latest hardware on this list is the Innosilicon T3 43T, which is currently available for pre-order at $2,279, and estimated to ship in March 2019. Offering 43TH/s of performance at 2,100W, the T3 43T comes in at an efficiency of 20.4GH/W, which is around 10 percent less energy efficient than the Ebit E11++.
The T3 43T also has a minimum order quantity of three units, making the minimum acquisition cost $6837 + shipping for preorders. All in all, the T3 43T is more costly and less efficient than the E11++ but may arrive slightly earlier since Ebang will not ship the E11++ units until at least end March 29, 2019.
Finally, this list would not be complete without including Bitmain’s latest offering, the Antminer S15-28TH/s, which — as its name suggests — offers 28TH/s of hash power while drawing just under 1600W at the wall. The Antminer S15 is one of the only SHA256 miners to use 7nm processors, making it somewhat smaller than some of the other devices on this list.
Like most pieces of top-end Bitcoin mining hardware, the Antminer S15 27TH/s model is currently sold out, with current orders not shipping until mid-February 2019. However, the S15 is offered at a significantly lower price than many of its competitors at just $1020 (excluding shipping), with no minimum quantity restriction. At these rates, the Antminer comes in at just $37.78/TH — though its energy efficiency is a much less impressive 17.5GH/W.

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

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

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

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

We are miners: There is a legend whose name is derived from King Arthur, meaning the world of bliss
We are an old leek, old miner! Being cut one after another, filling one by one, this thing is very fun, we are still playing.

From 2013 the present, the crypto mining circle is full of stories. Do you remember the butterfly mining machine that was pre-ordered a year later? Remember that the ASICMiner (friedcat) accounted for one-third of the world's hash rate in the BTCGuild mining pool?

In the interviewing ngzhang (Zhang Nangeng, the founder of Avalon) by Cybtc.com, he said,

"Avalon's name is derived from the legend of King Arthur, meaning the world of bliss."

Zhao Dong mentioned in the interview by Cybtc.com,

"I am not selling the house for the sake of speculation. I watched the property market, so I sold the house. I just touched Bitcoin, so I played Bitcoin. If I think that I am selling the house for the sake of speculation, it is a big misunderstanding."

On the 2013 Singles Day (Double eleven day), Bitmain announced that "55nm mining chip test was successful, power consumption is as low as 0.68w/gh/s, the upcoming spot ant mining machine".

Dream

The southwestern border of China is also known as Yunnan, also known as the south of the colorful clouds. The name of Cybtc.com, Colorful Yunnan Bitcoin" comes from here. There is beautiful scenery here, the climate of the four seasons like spring, the blue sky, the white clouds, there is abundant hydropower here. Resources. Every digital currency miner is profitable, but when you are in the arms of nature, watching a mining machine creak and calculating bitcoin transactions from around the world. This feeling is somewhat wonderful. The combination of high-tech and primitive nature will make you forget the difficulty of life, forget the pressure of work, and the feeling of magic and coziness is born. Feel like you don't want to leave, as Lijiang or Dali. In this deep valley, building a small house. The family is enjoying themselves in this pure nature. Sleeping early every day, sleeping until you wake up naturally. Soaking a pot of Pu'er tea, watching the river in front of you, let it be sinister in the world, all thrown into the brain Rear.

On the mining road: the rising sun shines above the sea of clouds.

On the mine road: enter the cloud, a pool of Jasper into the eye.

On the mine road: the lake and the autumn moon are two phases, and the windless mirror on the surface of the pond is not worn.

Reality

Brothers can wake up, it is a dream. The days of miners are actually very hard, Yunnan's highways and mountains are more curved. Every day, going to the mine to drive a mountain road for 10 hours is a common practice. You can see the piles of landslides everywhere. On the road beside the cliff, loneliness and loneliness hit the heart.

On the mine road: the altitude changes, the road surface is slippery.

I hope that the days of the miners will be better every day!

Chinese Miners Have Cartelized Chip Production

I rarely see this talked about if at all. Most ASICS since the time of ASICMINER have been produced in some capacity by TSMC. Ignoring NRE costs, which ironically isn't very high in comparison to chip production, most connected Chinese miners can get chips directly from fabrication.
When Avalon started shipping orders, they also shipped wholesale chips at 10,000 a Batch. Each Avalon chip at the time would generate about 0.4 BTC a month. The procurement cost was about 9 bucks per chip. Given it would cost you about 10-15 bucks to rig a single chip into a miner you were looking at a net ROI of about 20-21 bucks per month with increasing difficulty.
More details can be seen here.
Now it costs about $8-$10 per gigahash retail, which given the difficulty increase, and the fact the impact of NRE costs should be going down (given this expense is less impactful to revenue with the more chips you sell as it's a fixed cost), anyone buying a retail miner is getting fleeced.
I have seen less and less direct chip buys, to the point I'm convinced Bitcoin ASIC production has been cartelized.
The Chinese chip producers will effectively push smaller miners out of the market by over pricing hardware sales to the public, while giving their buddies the "at-cost" price.
The demise of KNC miner is due to miner cartelization.

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.
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.
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.
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:
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.
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
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.
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.
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.

German IRS going to JAIL ME:(

Hey guys, i was fucking in love with bitcoin and put about 30k euro(all what I had back then into btc, started way back when btc was 20-30usd and even bitcoin-24.com existed)
Well not all when it was so cheap back then but over more then a year time period
Well to make it short: I played a lot with my coins, bought shares of asicminer, made bad trades etc all that stupid stuff.
I was left with about 600 coins in mtgox when it went bankrupt. (The coins were in gox because I was about to buy a new laptop that I wanted to keep offline for ever(paper wallet style) to store my coins safe for ever. (Fuck i even thought my printer could be hacked -,-)
So before I managed to do this shit mtgox went bankrupt and all I had left was about 2000 € on my bank account.
Not a big problem since I lived of 400 euro a month (welfare since I lost my job few months before)
Well the goxxing was in januafebruary 2014 right? Back then I just fell into the deepest depressive phase that you can imagine (because my coins were woth more then a half million euro back then, well at least in my thinking:( )
and cried all day and just layed on my couch the whole day :( To make it even worst my best and only friend commited suicide in may 2014 and what went on were more months and months of pure ignore of the world and just sitting at home :(
I think it was july that I decided that my life cant go on this way so I sent my applications to universitys of applied science.. and taaaada I got my place and started to study health information management in germany!
September 2014 went on and I started to feel lucky again. University was kinda easy and I finished the first semester in february 2015 and passed all classes(30 credits)
The second semester went from march to july with the same success and right now iam in my third semester (september to february 2016)
Well why am I wriiting all this in broken english?
Today it hit me.
I received a letter from the german IRS (taxes) and they want all my bitcoin records. (I even sold some miners in 2013 via ebay) whatever.
I recognized the letter and right now iam sitting here crying for 6 hours.. Iam fucked. iam totally FUCKED Back in may 2014 I started to ignore and block bitcoin in my brain and decided to never think about again because I got so burnt emotionally.
I have no records left, NOTHING NOTHING Is there any way that I can at least extract my mtgox trading info somehow? I never made any profit, but I sold some miners and bought/sold bitcoins. My bank account from 2013-2014 looks like I made about 60k€ profit even thought I didnt made any profit because I put it back into bitcoins. I need all that trade history from gox or some female to marry me, so that I can leave this place;( I even sold some bitcoins via bitcoin.de and bought them back in gox just to spread bitcoins and make it popular, but right now itll look like I made a fuckton of money. I already see how my apartment gets raided if I cant give them enaugh records and I see myself in jail by summer 2016:((((((((((((((((((( (yeah I sold some avalon miners for 4-8k euro back in the days on ebay, without profit but to spread the fucking mining) But even that looks right now like a huge profit because I did never care about fucking records.

Tera Hash Rate is going to explode. What happens afterwards?

Bought myself a 5GH/s BFL miner. Not expecting to see it until June. Numbers like this make me fear even wanting to connect that device to my PC when I get it... Will it even be worth mining without a Mini Rig SC or Avalon at that point?
" In the next few months, Bitcoin network hashpower will only continue to increase. Avalon’s three shipments altogether will make up a total of 1500 units, or over 75 TH/s, and ASICMiner is planning 50 TH/s by the end of April, and 200 TH/s soon after. By the end of the year, ASICMiner’s friedcat writes on Bitcointalk, ASICMiner’s total hashpower may be as high as 1000 TH/s, and friedcat even adds that “some may say that 1,000TH/s at the end of this year is too conservative.” "

HaoBTC and ASICMINER, two largest mining farms

HaoBTC and ASICMINER, two largest mining farms
https://preview.redd.it/4em2av1yw9h11.png?width=646&format=png&auto=webp&s=5408280a960b80a756fe6fac8d9a41006e7bfcef
Currently, mining is a process of mining various types of currency, not just bitcoins, on huge production sites.
Earlier, it was possible to obtain cryptocurrency on an ordinary PC, but over time the labor intensity of the process increased, more miners appeared, and due to the complexity of the process and the increase in the scale of production, the equipment was improved and its cost therefore increased.
Mining farms produce computational activities using computer power (in most cases using video cards), the result is new "money".
The majority of those who mined the currency at its very inception have already become millionaires, and even billionaires, because the exchange rate has already reached, and even exceeded the mark of 10,000 dollars. Currently, it's still profitable to organize similar mining farms on home PCs, while they are able to recoup themselves.
Most of the mining farms are located in China (the reason is relatively low energy costs), as well as in Iceland.
The first is a mining farm ASICMINER located in 8 miles from the central district of Hong Kong, in the Kwaichun area. This farm occupies a relatively small area, but produces a huge amount of capacity, thanks to the latest technology. The basis of the farm is the racks, ASIC chips are located on them and produce the capacities that are necessary in the production of crypto currency.
The second large-scale farm is HaoBTC, located in China. This farm is not as equipped as the first, however, it produces a huge number of capacities.
This company announced the launch of Hash-Ex, a new bitcoin-exchange, offering customers to buy and sell a hash rait- part of the mining network of crypto-currencies. The minimum purchase is 1 tera hash, and such an opportunity is available not only to Chinese citizens, but also to all foreign users.
Xun Yue, Vice President of HaoBTC, states that they sold 10 petashash capacities, and the company itself is the only owner of equipment for currency management, in this regard does not depend on any external factors.
"We probably have one of the best farms in the world. Many publications have written about us. We work in the provinces of Sichuan and Xinjiang, we have tens of thousands of Avalon A6, we also use the Antminer S7 and S9, "Xun Yue said.
Initially, it seems that HaoBTC is a set of typical contracts for cloud mining, but the organization itself focuses on the fact that it has cheap electricity and does not charge funds for the use and maintenance of equipment.
According to ForkLog, in winter, a new mining farm was launched in China, its capacity reaches 140,000 kilowatts. One of its founders is Bitmain Technologies. Mining farms are gaining popularity as the currency itself, China in this regard remains the leader due to its relatively inexpensive electricity, without which it would be impossible to produce any crypto currency in the world.

Frequently Asked Question: What's an ASIC, FPGA?

So you're sick of just mining on your GPU, and not a fan of the electric bill after a month of mining? There has to be a better option out there than your loud GPU in your gaming computer. There is!
Shortly after GPUs became popular for bitcoin mining, enterprising folks started looking at other things they can re-purpose to mine bitcoins more efficiently. Around mid-year 2011, the first devices sprang up that are called FPGAs or Field Programmable Gate Arrays. These are nothing new to the hobbyist community, they've been around for a while for crackers and other security-conscious folks looking at ways to defeat cryptographic locks. Hey! I know something that uses cryptographic calculations to secure its network! BITCOINS! Yep, so some miners developed their own boards and slapped some FPGA chips on them (most commonly the Spartan-6), and wrote specific firmware and "bitstreams" to more efficiently calculate bitcoin hashes. The first generations were sort of slow, but still they had better efficiency than a GPU. Some of the latest generation included the Icarus boards, Cairnsmore, x6500, and ModMiner Quad.
In early 2012(i think my timeline is right), Butterfly Labs(BFL) was selling their own FPGA miner that hashed at 800 Mhash/s using 80 watts and only cost US$600 amazing! These grew very popular, but people could see that FPGAs still weren't the most efficient way to hash their shares. BFL then announced that they would be designing their own chips that would be orders of magnitude faster than anything ever seen. These would be the ASICs (or Application Specific Integrated Circuit)everyone is raving about. ASICs are--as the name implies--specifically designed for one thing, and one thing only. Bitcoins. This is all it can do, and can't really be repurposed like an FPGA to other applications. Who wouldn't want a US$150 "Jalapeno" that hashes at 3.5 GIGAhashes/s using only power from a USB port?? Crazy! So summer 2012, BFL says they will ship before Christmas. Various things happen and we now still don't have any confirmed ship dates from BFL.
A few other companies have sprouted up, ASICminer which I believe is developing their own chips to mine themselves, but in a responsible way as to not threaten the network with a sudden influx of hashing. bASIC was a fiasco that was developed by the creator of the ModMiner Quad(which is actually a fantastic miner, I own one, and love it.) where he took many preorders, promised lots of people amazing ASIC performance, but in early 2013 the stress of the whole endeavour got to him and he gave up, refunded money(I think it's still being refunded now, or maybe it's been cleared up already.)
Avalon is the only company we know has ASIC mining hardware in the wild. It is not certain exactly how many are out there, but they have been confirmed by independent sources. The Avalon units are expensive(75 BTC) and have been in limited production runs (or batches) of a few hundred units that were pre-sold out very quickly.
All of this info is gleaned from the Custom Hardware forum over at bitcointalk.org over the past year or so I've been involved in bitcoin. I may have some facts wrong, but this is the gist of the situation and hopefully gives you an insight on the state of the hardware war against bitcoin
Thanks for reading!

Want to invest in bitcoin but willing to accept more risk for more return? Maybe investing would be right for you!

As we all know, companies such as AsicMiner are currently kicking butt with their asics by releasing the eruptor blades and Erupter USB sticks for mining. This combined with their 28% or so of total hashing power for the entire bitcoin network is resulting in fantastic growth over the past few months, and their dividends are doing quite well.
If you are interested in shares of AsicMiner , check out either Direct Shares or Pass Through shares, which is just one share of AsicMiner. You can find them in auctions on bitcointalk as well as sites such as BTCT.TO
You can also get smaller shares known as micro shares. There are often times 1/100th of a full share so people can easier purchase them and provide an easier method for reinvesting dividends.
There are other shares too, such as AMC which just recieved a few Avalons they purchased a while ago. Keep in mind that the owners relations with others on the forum is quite poor and very unprofessional, so I would still consider it rather risky.
There are also companies which are not based on bitcoin but experimenting with it as a source of capital, such as KenilWorth on bitfunder, who are a mining company which finds raw material deposits and then sells them to another company (I think). The people with that company are VERY responsive on bitcointalk and seem to be very professional.
You can even if you wish bet on funds which are reliant upon BFL's shipping, such as HaveLock's Investments Mining Fund. The owner of that fund is also rather response on bitcointalk and is a very down to earth person from what I have seen. For example, they just purchased a single Jupiter rig from KnCMiner in an effort to diversify so if BFL fails they will not be destroyed.
They are also other funds out there which are designed to represent an amount of Mhash/s per each share, for example RedStarMining which aims to have 180 Ghash/s eventually, with each share containing 2.818 Mhash/s.
Also, a very cool thing about these funds is that they are very present on bitcointalk in the securities section, so you can see up to date discussion about each fund. For example, for red star mining, here is their thread: https://bitcointalk.org/index.php?topic=63257.0
You can even get a fund in an exchange, such as Crypto-Trade! Though, they seem to be having some major issues with their site for a while now, which is unfortuntate.
And you can get shares in the gambling site satoshidice!
There are tons of such securities available for lots of different styles people could choose, and because of bitcoin buying these shares is a very painless process. But do keep in mind that this is riskier than just holding bitcoin, and there are a good bit of scams prevalent in such securities, but if you keep an eye out and read their associated threads on bitcointalk you will be for the most part safe. Also, investing in companies like AsicMiner increases the network hash rate, making it even harder for a single entity to barge in and get more than 50% of the network hash rate, resulting in an even more secure network! These sometimes even hare shares which cost less than five dollars, so to get started you don't need much BTC at all.
And here is the link to bitcointalk for anyone who wants to do more research and look at any other funds which might be of interest. Don't forget that there are some funds which are not exchanged on these sites, for example group buys where each buyer holds a certain percentage of proceeds from a very expensive miner they pool together to buy. As earlier though, be careful.
There is also a really good subreddit for discussing these securities as well as others on /BitcoinStocks !
Edit: Added in bitcointalk threads for each security I listed.
Edit: It seems that there are nearly half as many downvotes as there are upvotes. Can anyone clarify?

Are the socalled "Bitcoin Block Erupter USB ASICminer" legitimate?

I've been interested in BitCoins for a while, but haven't quite taken the time to get to understand it fully. I recently found this on eBay, which looks a bit less complicated. Link for eBay auction Would this be a good "starting device", and would it be able to net in any profits? If so, how much (little)?

State of the Bitcoin community.

This may be a long post but I wanted to get a few things off my chest. Some of you may not like what I'm saying but if that's the case at least take the time to discuss it rather than downvoting me. I think that's what communities on Reddit lack - discussion is how we progress and sometimes it feels like all Reddit does is downvote instead of actually talking up.
Firstly - Bitcoin in the media.
It's no big news that Bitcoin was synonymous with Silk Road and the Deep Web for a while. You couldn't have one without the other. This lead to a lot of negative press for Bitcoin itself. I think it was handled quiet well, we showed the majority of people that Bitcoin was useable in a mainstream setting but I don't think we did enough. How often do we see the good features of Bitcoins like:
How often do we see these features? I recently saw a sign in my local shop saying they couldn't accept credit card payments due to high fees. Imagine if they knew about Bitcoin, as long as they have a computer or even access to one they could attract a wider audience.
I think we can do a lot more to give out a clearer message about Bitcoin. I think a lot of the fear comes from the fact that people don't understand it. If we spend more time educating then we can get a more positive image out there.
Secondly - Miners, their profitability and other issues.
Thirdly - exchanges and how they work.
Bitcoin for devs and merchants.
I think a lot of work needs to be done for Bitcoin devs. Unlike other documentation, I found Bitcoin very hard to follow when it comes to dev. I understand the basics of coding and a few languages - not a much but enough to say make a web page or a automated program in C#. Imagine if you had Bitcoin dev dedicated websites like w3schools does for languages (I know w3 schools is a very bad benchmark but whatever). If more people understood how dev works then more people would attempt to get into it.
I think a lot of work needs to be done within the BTC community itself before we even think of making it mainstream. Even if the last price reaches $1000 it's useless if people don't know as much as should do.

Bitcoin Mining

Hey reddit, I am interested in getting involved with mining Bitcoins. I understand that many people choose to buy miners rather than make one themselves. I have heard of Butterfly Labs miners, but I hear they are having manufacturing/shipping delays. I have heard people throw around words like "ASICMiner," "Avalon," etc., but what do these things mean? I have tried to search on Google but the information I receive is all about how mining works and not about any mining products. Can someone fill me in? Thanks!

Fallacy: Slower PoW is Safe from ASIC’s?

taken from https://litecointalk.org/index.php?topic=18166.0
The escalating “N” proposals all suffer from the issue where increasingly slow PoW by design makes it much slower to verify, thereby worsening block propagation latency across the multi-hop P2P network. Block propagation latency is already a growing problem on the Bitcoin network where larger blocks take longer to traverse the network. With an escalating memory PoW the smallest of blocks would suffer from increased propagation delay. At best this means increased annoyance from more frequent accidental orphans. At worst, higher propagation latency reduces the cost of perverse mining behaviors like double-spending attacks.
Furthermore it is doubtful that escalating N would be truly ASIC proof. Since the deployment schedule of future N is known, near-term ASIC’s could cut costs as they need not implement distant future N in hardware because early generation custom hardware will be unable to compete on power cost with later generation custom hardware. We already see this today with first generation Avalon and ASICMINER miners, currently so power cost uncompetitive that they are being given away at the cost of disposal.
-Is there any truth to this ? im guessing the second point could be invaladated by devs adding a fork..

bitcoin asic avalon miner 3 for sale.

I'm a bitcoin miner. Have been for the past 3 years and lets just say it was well worth it. Currently have 7 avalon asics running and a few usb asicminer usbs going. I'm looking for more avlaon miners. Will to pay 10-15k. I want yalls opinion on this link. This person is selling 3 avalon asics for 10,000 on bitmit.net. Do you think its legit? I messaged him and he wants to use the escrow service with the guy from bitcointalk so I trust that. I just feel like something might be wrong with the machines since they are only 10,000. shoot me your opinion. here is the link for the 3 miners https://www.bitmit.net/en/item/40712-avalon-asic

Announcing - MineNinja BeagleBone Bitcoin Mining Platform

Open Source startup CoinNinja (www.coinninja.com) launches its first product geared for miners of the Bitcoin crypto-currency. The MineNinja is a turn-key device for hosting Bitcoin mining hardware, such as ASICs from Butterfly Labs, Avalon, and ASICMiner. With the bitcoin mining market rapidly moving to ASIC devices which provide more Hash power per watt, the MineNinja is the perfect compliment as it further reduces power consumption by eliminating the need for a PC.
"We chose the BeagleBone Black over the Raspberry Pi as it is truly open source. The BeagleBone design is totally open, and that cannot be said about the Pi. Furthermore we found the BeagleBone to be far more reliable, and operating temperatures to be significantly lower.”
Leveraging the power of Open Source development, the MineNinja is a great example of the Maker revolution for innovative small business. The MineNinja is small batch manufactured using the Open Source BeagleBone Black from Texas Instruments and its enclosure is 3D printed on an open source RepRap 3d Printer. The MineNinja is so low-power that it can easily be powered using only a USB port.
"We believe in the Open Source movement, all of our hardware and software is fully open source. We encourage users to make their own MineNinja, everything needed to make your own be easily found in our Github repositiory." - states Alessandro Nardella, Lead Developer at CoinNinja.
The MineNinja leverages existing open source software such as Angstrom Linux, Cgminer and the ANUBIS web front-end to Cgminer. The MineNinja uses the BeagleBone Black without any hardware modifications, which allows users to further refine the product by adding their unique contributions.
The MineNinja BeagleBone Bitcoin miner is available today in limited quantities at www.mineninja.com.
