95.7% of all the bitcoin that will ever exist has already been mined. There were 20.10M BTC in circulation on Oct 28. That leaves about 895K still to come, spread out until around 2140. Half of all bitcoin, 10.5M, was mined before the first halving in November 2012. Since the fourth halving in April 2024, miners get 3.125 BTC a block, or about 450 a day. The next halving, expected in 2028, cuts that to about 225. New supply now adds about 0.8% a year to the pile, and that rate only shrinks from here. How many of those 20.1M coins are lost for good?
