Only 21 million bitcoins can be mined in total. Once the bitcoin miners have unlocked all the bitcoins, the planet's supply will be exhausted. And there will only be 21 million left in the future. Part of what makes bitcoin valuable is that it has a limited supply.
Only 21 million bitcoins will exist, each of which can be divided into 1,000 millibitcoins (mBTC), 1,000,000 microbitcoins (μBTC) or 100,000,000 Satoshis. Additional bitcoins cannot be created, and existing bitcoins cannot be destroyed, they can only be lost. The remaining Bitcoins that are not in circulation are given to miners as a reward for maintaining the integrity of the network. With only 21 million Bitcoins ever to exist, this means that there are about 13 million BTC in circulation or lost forever, so the new ones will be widely distributed.
As of today, the number stands at 2,868.After 64 total halvings, there will be no more Bitcoins left to reward miners and all 21 million Bitcoins will be in circulation. Since bitcoins can only be created by being mined, all bitcoins in existence are bitcoins that have been mined. This creates new bitcoins more quickly, so that most days more than 900 new bitcoins are created. Between lost, stolen and retained bitcoins, there are only about 8 million bitcoins left circulating in the current market.
With almost 90 percent of the entire supply of bitcoins already produced, in circulation or lost forever, there are not many of them left. If this trend continues, and the whales have no intention of selling their holdings, the amount of bitcoin left for the average citizen to buy will be very limited. Assuming all pools have similar numbers, there are likely to be more than 1,000,000 unique individuals mining bitcoins. New Bitcoins are created through a process called mining, which verifies Bitcoin transactions and adds them to the blocks of the Bitcoin block chain.
As a reward for doing this work, the miner who manages to add a block first receives a certain amount of Bitcoins. Since a new block is added to the Bitcoin blockchain approximately every 10 minutes, the total number of Bitcoins in circulation increases by
6.Unlike central banks, which can issue their currencies in any volume at their discretion, thus causing inflation, the number of Bitcoins is increasing at a stable, predictable and periodically decreasing rate. According to a study by the blockchain analysis company Chainalysis, there are about 4 million Bitcoins that have been irretrievably lost. In addition, many Bitcoin holders, including large ones, prefer not to use their Bitcoins as a means of payment.
