Bitcoin supply is limited to 21 million. In fact, there are only 21 million bitcoins that can be mined in total. There are bitcoins left to be mined. However, bitcoins can always be bought from existing users on the exchanges.
As of today, the number stands at 2,868.With only 21 million Bitcoins that will exist, this means that there are around 13.And this counts the coins lost due to the loss of private keys, the blocked coins of Satoshi, and due to the death of the HODLer. With almost 90 e all the BTC that have ever existed already in circulation or lost forever, the new ones will be very spread out. 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 being mined, 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. Once there are no Bitcoins left for the mining reward, transaction fees should be high enough as an incentive for miners to continue operating in the network. This creates new bitcoins more quickly, so that on most days more than 900 new bitcoins are created. 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. Every four years, the number of Bitcoins produced per block (a new block is created every 10 minutes) is halved. Considering that the creator of Bitcoin would have access to the coins, he would own more than 5 percent of the total amount of Bitcoins in existence. Because of this, the last bitcoin will be mined in the year 2140 and after that, no new bitcoins can be mined according to the Bitcoin protocol limit.
Due to the rarity and limited supply of Bitcoin, everyone in the cryptosphere is still excited about the number of bitcoins that have been mined and also lost. The remaining Bitcoins that are not in circulation are given to miners as a reward for maintaining the integrity of the network. On the other hand, the technical incompetence shown by an exchange similar to Coinbase is another reason for the lost bitcoins.
