We've reached a significant milestone.
As of May 2025, 93.3 percent of of the total supply has been mined, namely, 19.6 million Bitcoin have been mined.
Due to the halving, the mining rate is designed to gradually slow down through time.
It took around 15 years to get from 0 to 20+ million, but it'll take another over 100 years to get to 21 million, which at this rate is going to happen in 2140.
Because the early rewards were so large, over 87% of the total supply was mined by the end of 2020.
A lot of people believe, quite firmly, that this is a key component to making Bitcoin valuable, which might be true.
Or not.
We'll find out soon enough.
