It's worth noting that it is projected to take more than years before the bitcoin network mines its very last token. In actuality, as the year approaches, miners will likely spend years receiving rewards that are actually just tiny portions of the final bitcoin to be mined. The dramatic decrease in reward size may mean that the mining process will shift entirely well before the deadline.
It's also important to keep in mind that the bitcoin network itself is likely to change significantly between now and then. Considering how much has happened to bitcoin in just a decade, new protocols, new methods of recording and processing transactions, and any number of other factors may impact the mining process.

Table of Contents Expand. Bitcoin Mining Rewards. Effects of Finite Bitcoin Supply. Special Considerations. Key Takeaways There are only 21 million bitcoins that can be mined in total. Once bitcoin miners have unlocked all the bitcoins, the planet's supply will essentially be tapped out.
Once all Bitcoin has been mined the miners will still be incentivized to process transactions with fees. Article Sources. Investopedia requires writers to use primary sources to support their work.

Related Terms Bitcoin Mining Definition Breaking down everything you need to know about Bitcoin mining, from blockchain and block rewards to Proof-of-Work and mining pools. These fees ensure that miners still have the incentive to mine and keep the network going.
The idea is that competition for these fees will cause them to remain low after halvings are finished. These halvings reduce the rate at which new coins are created and, thus, lower the available supply. This can cause some implications for investors, as other assets with low supply—like gold—can have high demand and push prices higher. At this rate of halving, the total number of bitcoin in circulation will reach a limit of 21 million, making the currency entirely finite and potentially more valuable over time.
In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things have to occur. First, they must verify one megabyte MB worth of transactions, which can theoretically be as small as one transaction but are more often several thousand, depending on how much data each transaction stores.
Second, in order to add a block of transactions to the blockchain, miners must solve a complex computational math problem, also called a "proof of work. In other words, it's a gamble. The difficulty level of the most recent block as of August is more than 16 trillion. That is, the chance of a computer producing a hash below the target is 1 in 16 trillion. To put that in perspective, you are about 44, times more likely to win the Powerball jackpot with a single lottery ticket than you are to pick the correct hash on a single try.
Fortunately, mining computer systems spit out many hash possibilities. Nonetheless, mining for bitcoin requires massive amounts of energy and sophisticated computing operations. The difficulty level is adjusted every blocks, or roughly every 2 weeks, with the goal of keeping rates of mining constant. The opposite is also true. If computational power is taken off of the network, the difficulty adjusts downward to make mining easier.
Say I tell three friends that I'm thinking of a number between 1 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 the number I am thinking of. 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. Not only do bitcoin miners have to come up with the right hash, but they also have to be the first to do it. Because bitcoin mining is essentially guesswork, arriving at the right answer before another miner has almost everything to do with how fast your computer can produce hashes.
Just a decade ago, bitcoin mining could be performed competitively on normal desktop computers. Over time, however, miners realized that graphics cards commonly used for video games were more effective and they began to dominate the game. In , bitcoin miners started to use computers designed specifically for mining cryptocurrency as efficiently as possible, called Application-Specific Integrated Circuits ASIC.
These can run from several hundred dollars to tens of thousands but their efficiency in mining Bitcoin is superior. Today, bitcoin mining is so competitive that it can only be done profitably with the most up-to-date ASICs. Even with the newest unit at your disposal, one computer is rarely enough to compete with what miners call "mining pools. A mining pool is a group of miners who combine their computing power and split the mined bitcoin between participants. A disproportionately large number of blocks are mined by pools rather than by individual miners.
Mining pools and companies have represented large percentages of bitcoin's computing power. Consumers tend to trust printed currencies. In addition to a host of other responsibilities, the Federal Reserve regulates the production of new money, and the federal government prosecutes the use of counterfeit currency. Even digital payments using the U. When you make an online purchase using your debit or credit card, for example, that transaction is processed by a payment processing company such as Mastercard or Visa.
In addition to recording your transaction history, those companies verify that transactions are not fraudulent, which is one reason your debit or credit card may be suspended while traveling. Bitcoin, on the other hand, is not regulated by a central authority. Nodes store information about prior transactions and help to verify their authenticity. Unlike those central authorities, however, bitcoin nodes are spread out across the world and record transaction data in a public list that can be accessed by anyone.
Between 1 in 16 trillion odds, scaling difficulty levels, and the massive network of users verifying transactions, one block of transactions is verified roughly every 10 minutes. The bitcoin network is currently processing just under four transactions per second as of August , with transactions being logged in the blockchain every 10 minutes.
At that point, waiting times for transactions will begin and continue to get longer, unless a change is made to the bitcoin protocol. There have been two major solutions proposed to address the scaling problem. Developers have suggested either 1 creating a secondary "off-chain" layer to Bitcoin that would allow for faster transactions that can be verified by the blockchain later, or 2 increasing the number of transactions that each block can store.
With less data to verify per block, the Solution 1 would make transactions faster and cheaper for miners. Solution 2 would deal with scaling by allowing for more information to be processed every 10 minutes by increasing block size. The program that miners voted to add to the bitcoin protocol is called a segregated witness , or SegWit.
Less than a month later in August , a group of miners and developers initiated a hard fork , leaving the bitcoin network to create a new currency using the same codebase as bitcoin. Although this group agreed with the need for a solution to scaling, they worried that adopting segregated witness technology would not fully address the scaling problem. Instead, they went with Solution 2.
For this reason, there will only ever be 21 million bitcoins ever produced. On average, these bitcoins are introduced to the bitcoin supply at a fixed rate of one block every ten minutes. In fact, there are only 21 million bitcoins that can be mined in total. However, it's possible that bitcoin's protocol will be changed to allow for a larger supply. What will happen when the global supply of bitcoin reaches its limit? This is the subject of much debate among fans of cryptocurrency.
Currently, around This leaves less than three million that have yet to be introduced into circulation. While there can only ever be a maximum of 21 million bitcoin, because people have lost their private keys or have died without leaving their private key instructions to anybody, the actual amount of available bitcoin in circulation could actually be millions less.
The first With only three million more coins to go, it might appear like we are in the final stages of bitcoin mining. This is true but in a limited sense. While it is true that the large majority of bitcoin has already been mined, the timeline is more complicated than that. The bitcoin mining process rewards miners with a chunk of bitcoin upon successful verification of a block.
This process adapts over time. When bitcoin first launched, the reward was 50 bitcoin. In , it halved to 25 bitcoin. In , it halved again to On May 11, , the reward halved again to 6. This effectively lowers Bitcoin's inflation rate in half every four years. The reward will continue to halve every four years until the final bitcoin has been mined. In actuality, the final bitcoin is unlikely to be mined until around the year However, it's possible the bitcoin network protocol will be changed between now and then.
The bitcoin mining process provides bitcoin rewards to miners, but the reward size is decreased periodically to control the circulation of new tokens. It may seem that the group of individuals most directly affected by the limit of the bitcoin supply will be the bitcoin miners themselves. Some detractors of the protocol claim that miners will be forced away from the block rewards they receive for their work once the bitcoin supply has reached 21 million in circulation.
But even when the last bitcoin has been produced, miners will likely continue to actively and competitively participate and validate new transactions. The reason is that every bitcoin transaction has a transaction fee attached to it. These fees, while today representing a few hundred dollars per block, could potentially rise to many thousands of dollars per block, especially as the number of transactions on the blockchain grows and as the price of a bitcoin rises. Ultimately, it will function like a closed economy , where transaction fees are assessed much like taxes.
It's worth noting that it is projected to take more than years before the bitcoin network mines its very last token. In actuality, as the year approaches, miners will likely spend years receiving rewards that are actually just tiny portions of the final bitcoin to be mined. The dramatic decrease in reward size may mean that the mining process will shift entirely well before the deadline. It's also important to keep in mind that the bitcoin network itself is likely to change significantly between now and then.
