Are bitcoins worth mining

While rewards will cease at that time, fees will be introduced which will compensate miners for their continuous work on the network. The aforementioned reduction of Bitcoin rewards through mining also regulates the supply rate of new Bitcoin. You have set up your machine and have begun mining. Does any amount of time spent mining equal a proportional amount of Bitcoin earned?

Not exactly. To be eligible for a block reward, you have to fulfil two distinct requirements. One, you must verify transactions totalling up to one megabyte in size, oftentimes involving the verification of hundreds or thousands of unique transitions. Two, you must solve the aforementioned complex mathematical problem.

This step ensures that you have done the work, in a way. How complex is this problem? It basically involves a 64 digit hexadecimal number a hash and your machine attempting to either match that or come up with a number that is lower than the target number. Your machine cannot find a targeted way to do this. It will simply throw out random numbers until a match is found.

How difficult is this? Well, in August last year, the difficulty level was akin to having one guess to pick the correct number out of 16 trillion numbers. Of course, computers can come up with multiple numbers simultaneously but it still requires huge amounts of energy and extremely advanced processing power for the required computing operations to take place.

Moreover, the difficulty level is not constant. It is adjusted every blocks, which usually equates to around 14 days. The more people who are trying to mine Bitcoin exist, the harder the difficulty level becomes. The adjustment process also takes into account a reduction in the total computational power within the network. Well, not exactly. In the early stages of the cryptocurrency being introduced efficient mining could have been conducted in normal computers found in everyday households. However, this is no longer the case, as Bitcoin mining has become extremely competitive.

This is one of the reasons why top-of-the-line graphics cards have become less affordable or perhaps less available over time. I recall an instance where a friend purchased a high-end graphics card for his gaming rig after it was placed on discount, with the retailer then cancelling all discounted sales of the graphics card, refunding all buyers, and then placing them back on sale at a price higher than its pre-discount value.

At this point, however, even advanced gaming rights are not enough to mine Bitcoin competitively. ASICs are created and designed specifically with Bitcoin mining in mind. Although ASICs can also be designed to mine other cryptocurrencies as well, each machine is configured for the mining of one specific cryptocurrency. So how much do ASIC mining machines cost? A solid ASIC machine with a hash power of 8. Moreover, some miners can pool their processing power together and then share the profits accordingly.

Whether Bitcoin mining makes sense to you in depends on your resources and general outlook on Bitcoin in general. This is not a case of bypassing a clothes retailer by sewing your own suit. The situation is more complex than that. The bad news: It's guesswork, but with the total number of possible guesses for each of these problems being on the order of trillions, it's incredibly arduous work. In order to solve a problem first, miners need a lot of computing power.

That is a great many hashes. 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. In addition to lining the pockets of miners and supporting the bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of Nov. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin.

There will eventually come a time when Bitcoin mining ends; per the Bitcoin Protocol, the total number of bitcoins will be capped at 21 million. This does not mean that transactions will cease to be verified.

Miners will continue to verify transactions and will be paid in fees for doing so in order to keep the integrity of Bitcoin's network. Aside from the short-term Bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol. The rewards for bitcoin mining are reduced by half every four years. When bitcoin was first mined in , mining one block would earn you 50 BTC.

In , this was halved to 25 BTC. By , this was halved again to If you want 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. Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, 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 smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one 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 Bitcoin, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in the initial difficulty level was one.

As of Nov. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC. The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring fans.

Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money. The ins and outs of bitcoin mining can be difficult to understand as is. 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. 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 who haven't verified the most transactions are not rewarded with bitcoin. Well, 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. As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, 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. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f. 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 ELI5 analogy, where I wrote the number 19 on a piece of paper and put it 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. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about.

In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. 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 was mined.

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 transactions for this block.

If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros.

There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. You'd 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 those 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.

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. 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. Source: Cryptocompare. Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion 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 Bitcoin network will be capped at 21 million total bitcoin. This has been a key stipulation of the entire ecosystem since it was founded, and the limit is put in place to attempt to control for supply of the cryptocurrency. Currently, over 18 million bitcoin have been mined. As a way of controlling the introduction of new bitcoin into circulation, the network protocol halves the number of bitcoin rewarded to miners for successfully completing a block about every four years.

In , this number was halved and the reward became In , it halved again to In May , the reward halved once again to 6. Bitcoin mining can still make sense and be profitable for some individuals. 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.

The variables needed to make this calculation are:. 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 value of bitcoins. Also, change the level of difficulty to see how that impacts the analysis.

Determine at what price level bitcoin mining becomes profitable for you—that is your breakeven price. Given a current reward of 6. Of course, as 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 in mining, putting profitability in reach. As difficulty and cost have increased, more and more individual miners have opted to participate in a pool. While 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.

To answer the question of whether bitcoin mining is still profitable, use a web-based profitability calculator to run a cost-benefit analysis. You can plug in different numbers and find your breakeven point after which mining is profitable. 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 in receiving bitcoins.

When bitcoin prices and mining difficulty rise, expect the opposite—more miners competing for fewer bitcoins. Congressional Research Service. Accessed May 17, Your Money. Personal Finance.

The miner may never recoup their investment. The answer to this problem is mining pools. 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 miner. As mentioned above, the easiest way to acquire bitcoin is to simply buy it on one of the many exchanges. Alternately, you can always leverage the "pickaxe strategy. Or, 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 legality of Bitcoin mining depends entirely on your geographic location. The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places.

Bitcoin ownership and mining are legal in more countries than not. The risks of mining are that of financial risk and a regulatory one. As mentioned, Bitcoin mining, and mining in general, is a financial risk. 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 that it is prohibited you should reconsider.

It may also be a good idea to research your countries regulation and overall sentiment towards cryptocurrency before investing in mining equipment. Your Money. Personal Finance. Your Practice. Popular Courses. Part Of. Bitcoin Basics. Bitcoin Mining. How to Store Bitcoin.
