In fact, there are only 21 million bitcoins that can be mined in total. And there will only be 21 million in the future. The Bitcoin source code determines how many bitcoins are left. 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 that will ever exist, this means that there are around 13 million Bitcoins left in circulation. As of today, the number stands at 2,868.With almost 90 percent of all the BTC that ever existed already in circulation or lost forever, the new ones will be distributed very little. At the time of writing, there are 18,483,118 Bitcoins, although this number is constantly increasing. New Bitcoins are created through a process called mining, which verifies Bitcoin transactions and adds them to the blocks in 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. After 64 total halvings, there will be no more Bitcoins left to reward the miners and all 21 million Bitcoins will be in circulation. Since bitcoins can only be created by mining, all bitcoins in existence are bitcoins that have been mined. One of the main characteristics of the Bitcoin currency is its limited supply, so it is important to know how many Bitcoins are left.
This causes new bitcoins to be created more quickly, so that most days more than 900 new bitcoins are created. Additional bitcoins cannot be created, and existing bitcoins cannot be destroyed, they can only be lost. Bitcoins can be lost if their owner loses the private key of a paper or other cold-storage wallet, or if bitcoins are stored on a hard drive or wallet that is lost. The private key is needed to send bitcoins from one wallet to another, so without it, bitcoins cannot be used or sold.
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, it is likely that there are more than 1,000,000 unique individuals mining bitcoins.
Given that a new block is added to the Bitcoin blockchain approximately every 10 minutes, it follows that the total number of Bitcoins in circulation increases by
Unlike central banks, which can issue their currencies in any volume at their discretion, thus causing inflation, the number of bitcoins increases at a stable, predictable and periodically decreasing rate.
