It took almost 13 years to reach this milestone since the first BTC were mined on January 9, 2009. It will take more than 100 years to mine the remaining 10% of BTCs! The reason is that the difficulty of mining is increasing every year, while the issue rate is halving every 4 years.
- 95% will be mined in ~December 2025
- 99% will be mined in ~february 2035
- 99.9% will be mined in ~January 2048
- The last whole bitcoin will be mined in 2105
- All bitcoins will be mined in 2139
The main value of BTC is a limited number of coins. There will never be more than 21,000,000 BTCs in the world. So far, few people realize how small that is. Only 10% or 2,100,000,000 bitcoins remain to be created. They are not just limited.
The number of Bitcoins in circulation is constantly decreasing due to lost wallets or other reasons. About 3.79 million BTC are permanently lost, and 1 million Bitcoins are stored in the addresses of Satoshi Nakamoto, the creator of the main cryptocurrency.
It means almost 5 million BTC out of 21 million are not involved in circulation, which increases the value of the coins even more. There will be even more lost BTCs in the future. But there is one plus: when someone loses BTC, he increases the value of all other coins.
