Amount of bitcoin in circulation
As of April , the number of Bitcoins that have been mined reached 19 million. When the number of Bitcoin reaches 21 million, the mining activity will end. Experts predict that all Bitcoin production will end in , as production halves on average every four years.

Cryptocurrency mining has drawn criticism from climate activists for the energy it consumes and its impact on the environment. Instead, the code Bitcoin uses rounds decimal points to the closest integer. As a result, a supply of 6. Bitcoins are split into smaller units, known as satoshis. Due to these smaller units — and the rounding off of figures — experts suggest the Bitcoin supply cap will be limited to 20,, instead of 21 million Bitcoins.
Is the Amount of Bitcoin Fixed? Total Bitcoin supply and the maximum number of Bitcoins up for mining are fixed — unless the stakeholders decide to do something about it. When Satoshi Nakamoto invented the virtual currency, he did it as an open-source project. Despite the incentive to do so, the potential impact of such a change is highly debatable and controversial.
The incentive is paid in block rewards, which is a fixed number of Bitcoins distributed to miners. Besides receiving Bitcoin, miners also receive a part of the transaction fees associated with a block. When the currency was launched, the reward was 50 Bitcoins for confirming a block of transactions. After four years, this reduced to 25 bitcoins, and this cycle will continue until there are no more bitcoins left to mine.
Currently, after three halvings, miners receive 6. Despite the reduction in reward, the higher value of each Bitcoin makes up for the halving effect. Transaction fees have also increased as a result of Bitcoin going mainstream. While Bitcoin transaction fees are expected to rise, it is not necessary for all Bitcoin transactions to be settled to the blockchain. Additional layers such as the Lightning Network provide cheaper, faster ways of transferring bitcoin and will likely help with mass adoption.
There is no doubt that getting block rewards is a major incentive for miners. This monetary incentive not only keeps miners interested in mining, but also helps the entire ecosystem thrive. Under these circumstances, it makes perfect sense to ask what may happen when all of the Bitcoins have been mined.
Since Bitcoin itself is software, experts agree that it can be changed. To do it will require developers, stakeholders and the community at large to agree to alter the code. If an agreement were to be reached, the developers would write a code to integrate those changes in the Bitcoin Core.
For everything to work properly, the next step would be to ensure that all nodes on the Bitcoin network accept the changes — or are forced off the network. However, getting every node to accept the changes is no trivial task, since the Bitcoin platform was primarily designed as a stand-alone system that requires no changes.
At this stage, the developers would need to deal with a hard fork. A hard fork is a consensus change that makes a previously invalid behavior valid. In the perfect scenario, all the nodes would be upgraded to accept the proposed changes. Another scenario would have only some Bitcoin users favoring the existing 21 million Bitcoin limit.
These dissidents would likely compete with the new Bitcoin platform to capture market share. This is known as a contentious hard fork as it would create another chain that splits the miner base, and one such example is Bitcoin cash. Irrespective of any future efforts to change the underlying Bitcoin Core, experts continue to speculate on the future once the maximum limit is reached.
Several analysts favor the idea of using higher transaction fees to compensate for the absence of block rewards. New technologies will likely help to cut the cost of mining, which will eventually result in more profit for miners.
Another theory suggests that Bitcoin platforms will only be used for large transactions of very high value, which will offer sufficient revenue to keep stakeholders satisfied. There are other theories as well which speculate about proof of stake and mining cartels. Miners Miners are responsible for keeping the Bitcoin blockchain alive and updated through mining. Mining is the process of verifying transactions and adding new blocks to the Bitcoin network.
In order to do this, Miners have to solve complex mathematical puzzles which nowadays require costly ASIC computers to produce large computational powers and also uses a lot of electricity. To compensate for their effort and cost to secure the network, miners are awarded block rewards a set number of bitcoins and transaction fees. Currently, most miners and mining firms use this block reward to offset the cost of mining and still make a profit. But as mining rewards are halved every four years, it is expected that bitcoin mining costs will eventually exceed the bitcoin rewards that miners make, way before the fixed supply is reached.
However, if the price of bitcoin increases enough over time, it can offset a decrease in block rewards. All miners from the previous generation of to are no longer profitable and many of the mining rigs between and are also no longer profitable. As of this writing, companies that had ambitious growth plans in and placed large orders of bitcoin mining equipment orders and built expensive infrastructure may not be profitable and may have to continuously sell their bitcoin reserves or take out loans against their Bitcoin, ASIC miners or even infrastructure in order to stay afloat.
In the next Bitcoin halving around , these breakeven prices will double if more efficient mining rigs are not created or cheaper sources of electricity are not found, and this could spell trouble for miners if Bitcoin does not increase enough to reach those levels, creating a potential death spiral for Bitcoin. A Bitcoin death spiral is where too many miners stop mining as it becomes unprofitable and there is not enough hashpower to mine sufficient blocks for the mining difficulty to readjust within 2 weeks, however this is a highly improbable event.
If other miners are forced to shutdown due to the halving, miners who managed to remain profitable should see increased returns because their relative share of the total hash rate has risen. When the total hash rate declines, the difficulty of mining declines as well. For miners who continue to mine, a halving can increase profitability by weeding out competition and increasing their likelihood of finding a block and claiming the reward.
The only question is, what happens when all the coins are mined. Theoretically, if a miner validates enough transactions, the fees earned can help make up for the missing block rewards.

Since the owner needs to protect their Bitcoin using wallets and passwords, there is no way to access the stored Bitcoins if the owner passes away without giving someone else access to the password. The source code he wrote comes with a unique condition — a hard limit on the number of Bitcoin that can ever be produced. Since inception, every aspect of the Bitcoin network has been in a continuous process of maturation, optimization, and specialization, and it amount of bitcoin in circulation be expected to remain that way for some years to come. Which means, in the face of rising popularity, the price of cryptocurrency will surge as more people buy into the concept. An artificial over-valuation that will lead to a sudden downward correction constitutes a bubble. Instead of the take-it-or-leave-it approach, policymakers will probably favor a middle ground, such as approving a Bitcoin ETF. |
