In an effort to stay competitive, some machines have adapted. For example, some hardware allows users to alter settings to lower energy requirements, thus lowering overall costs. Prospective miners should perform a cost-benefit analysis to understand their break-even price before making the fixed-cost purchases of the equipment. The variables needed to make this calculation are:. There are several web-based profitability calculators, such as the one provided by CryptoCompare, that would-be miners can use to analyze the cost-benefit equation of Bitcoin mining.
Profitability calculators differ slightly, and some are more complex than others. Run your analysis several times using different price levels for both the cost of power and the value of bitcoins. Also, change the level of difficulty to see how that affects the analysis.
Determine at what price level Bitcoin mining becomes profitable for you—that is, your break-even price. Given a current reward of 6. Of course, because the price of bitcoin is highly variable, this reward figure is likely to change. To compete against the mining mega centers, individuals can join a mining pool , which is a group of miners who work together and share the rewards. This can increase the speed and reduce the difficulty of mining, putting profitability in reach.
As difficulty and cost have increased, more and more individual miners have opted to participate in a pool. Although the overall reward decreases because it is shared among multiple participants, the combined computing power means that mining pools stand a much greater chance of actually completing a hashing problem first and receiving a reward in the first place.
The two most commonly used payout methods used in Bitcoin mining pools are briefly described below:. As bitcoin's ecosystem has developed, a new form of payment method has developed to overcome drawbacks inherent in both payment method types. For example, a pay-per-share model can remove the incentives for miners from finding blocks altogether since a payout is guaranteed. A proportional mining method is problematic during bear markets or as bitcoin rewards decline.
In response, many miners have taken to switching their resources between mining pools based on their payout method and bitcoin price. Some mining pools have also adapted their rewards strategy between the two payout methods in response to declining rewards of bitcoin.
To answer the question of whether Bitcoin mining is still profitable, use a web-based profitability calculator to run a cost-benefit analysis. Determine if you are willing to lay out the necessary initial capital for the hardware and estimate the future value of bitcoins as well as the level of difficulty. When both Bitcoin prices and mining difficulty decline, it usually indicates fewer miners and more ease of receiving bitcoins.
When Bitcoin prices and mining difficulty rise, expect the opposite—more miners competing for fewer bitcoins. Even more telling is another statistic from the research: 0. This means that bitcoin rewards are distributed disproportionately in bitcoin's network. When you sign up to mine independently, bear in mind that you are competing against established outfits that have enormous capacity, amounting to megawatts, at their disposal.
Bitcoin mining is the process by which miners earn bitcoins in exchange for running the verification process to validate bitcoin transactions. It involves solving math puzzles and requires the application of brute force, in the form of computing power, to solve.
During the early days of Bitcoin, mining could be a profitable activity for individual miners. With an increase in difficulty levels of Bitcoin's algorithm and entry of large institutional players into the bitcoin mining ecosystem, its economics have changed, and it is now dominated by mining pools.
Individual miners should perform a cost-benefit analysis, taking into account variables—electricity costs, efficiency, bitcoin price—before committing to the activity. Bitcoin mining is the process of earning bitcoins by running the verification process to validate Bitcoin transactions. Miners earn rewards in the form of bitcoin for running the validation process. In the early days of Bitcoin, when it was mined using CPUs and the difficulty levels for its algorithm were easy, a rising price for the cryptocurrency ensured that mining was profitable for individual miners.
An increase in difficulty levels of the cryptocurrency's algorithm has skyrocketed electricity costs for mining operations and made the activity uneconomic for individual miners. In the main, there are three variables needed to calculate bitcoin profitability:. Two other factors that influence bitcoin mining profitability are the difficulty level of its mining algorithm and bitcoin price.
The two most common payout methods for mining pools are pay-per-share and proportional mining. A third payout method is a combination of the two. Congressional Research Service.

Bitcoin vs. Other Cryptocurrencies. Bitcoin Value and Price. Key Takeaways Bitcoin is mined using computing rigs, which include expensive hardware. Miners are rewarded with Bitcoin for verifying blocks of transactions to the blockchain network. As more miners compete for Bitcoin rewards, the process becomes more difficult.
To determine whether Bitcoin mining is profitable for you, consider costs of equipment and electricity as well as the difficulty associated with mining and how the price of bitcoin will affect potential rewards. Article Sources. In , this was halved to 25 BTC. By , this was halved again to On May 11, , the reward halved again to 6.
Not a bad incentive to solve that complex hash problem detailed above, it might seem. To keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real time. Interestingly, the market price of Bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and, historically, the price has risen with it.
If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site CryptoCompare offers a helpful calculator. Other web resources offer similar tools. Although individuals were able to compete for blocks with a regular at-home personal computer early on in Bitcoin's history, this is no longer the case.
The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the blockchain functions smoothly and can process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are 1 million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem.
For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate.
Less computing power means the difficulty level decreases. At today's network size, a personal computer mining for bitcoin will almost certainly find nothing. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a graphics processing unit GPU or, more realistically, an application-specific integrated circuit ASIC.
Some miners—particularly Ethereum miners—buy individual graphics cards as a low-cost way to cobble together mining operations. Today, Bitcoin mining hardware is almost entirely made up of ASIC machines, which in this case, specifically do one thing and one thing only: Mine for bitcoins.
Today's ASICs are many orders of magnitude more powerful than CPUs or GPUs and gain both more hashing power and energy efficiency every few months as new chips are developed and deployed. Say I tell three friends that I'm thinking of a number between one and , and I write that number on a piece of paper and seal it in an envelope.
My friends don't have to guess the exact number; they just have to be the first person to guess any number that is less than or equal to it. And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of Now imagine that I pose the "guess what number I'm thinking of" question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners, and I'm thinking of a digit hexadecimal number.
Now you see that it's going to be extremely hard to guess the right answer. If B and C both answer simultaneously, then the system breaks down. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions.
The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but haven't verified the most transactions are not rewarded with bitcoin. Here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet.
Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. The decimal system uses factors of as its base e. This, in turn, means that every digit of a multi-digit number has possibilities, zero through In computing, the decimal system is simplified to base 10, or zero through nine.
In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash. Remember that analogy, in which the number 19 was written on a piece of paper and put in a sealed envelope? In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash.
What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as quickly as possible. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep mentioning.
In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on Earth would you want to do that?
The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block No. The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by AntPool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below.
As you see here, their contribution to the Bitcoin community is that they confirmed 1, transactions for this block. If you really want to see all 1, of those transactions for this block, go to this page and scroll down to the Transactions section. Source : Blockchain. All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol.
No target can be greater than this number:. The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined by the mining difficulty. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. To find such a hash value, you have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined Bitcoin.
Mining pools are comparable to Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes.
At today's difficulty levels, the odds of finding the winning value for a single hash is one in the tens of trillions. Not great odds if you're working on your own, even with a tremendously powerful mining rig. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, but they must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution.
All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing. The site CryptoCompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits.

The miner who discovers a solution to the puzzle first receives the mining rewards, and the probability that a participant will be the one to discover the solution is equal to the proportion of the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0.
With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners.
By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miners. Statistics on some of the mining pools can be seen on Blockchain. As mentioned above, the easiest way to acquire Bitcoin is to simply buy it on one of the many Bitcoin exchanges. Alternately, you can always leverage the "pickaxe strategy. To put it in modern terms, invest in the companies that manufacture those pickaxes.
In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining. The risks of mining are often financial and regulatory. As aforementioned, Bitcoin mining, and mining in general, is a financial risk because one could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment.
That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area where it is prohibited, you should reconsider. It may also be a good idea to research your country's regulation and overall sentiment toward cryptocurrency before investing in mining equipment.
One additional potential risk from the growth of Bitcoin mining and other PoW systems as well is the increasing energy usage required by the computer systems running the mining algorithms. Though microchip efficiency has increased dramatically for ASIC chips, the growth of the network itself is outpacing technological progress.
As a result, there are concerns about Bitcoin mining's environmental impact and carbon footprint. There are, however, efforts to mitigate this negative externality by seeking cleaner and green energy sources for mining operations such as geothermal or solar sources , as well as utilizing carbon offset credits. Switching to less energy-intensive consensus mechanisms like proof-of-stake PoS , which Ethereum has transitioned to, is another strategy; however, PoS comes with its own set of drawbacks and inefficiencies, such as incentivizing hoarding instead of using coins and a risk of centralization of consensus control.
Mining is a metaphor for introducing new bitcoins into the system because it requires computational work just as mining for gold or silver requires physical effort. Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain. Because they are entirely digital records, there is a risk of copying, counterfeiting, or double-spending the same coin more than once.
Mining solves these problems by making it extremely expensive and resource-intensive to try to do one of these things or otherwise "hack" the network. Indeed, it is far more cost-effective to join the network as a miner than to try to undermine it. In addition to introducing new BTC into circulation, mining serves the crucial role of confirming and validating new transactions on the Bitcoin blockchain.
This is important because there is no central authority such as a bank, court, government, or anything else determining which transactions are valid and which are not. Instead, the mining process achieves a decentralized consensus through proof of work PoW. In the early days of Bitcoin, anybody could simply run a mining program from their PC or laptop.
But as the network got larger and more people became interested in mining, the mining algorithm became more difficult. This is because the code for Bitcoin targets finding a new block once every 10 minutes, on average. If more miners are involved, the chances that somebody will solve the right hash quicker increases, and so the difficulty increases to restore that minute goal.
Now imagine if thousands, or even millions more times that mining power joins the network.
