Bitcoin passes 20 million mined coins as remaining supply falls below 1 million BTC
Bitcoin has surpassed 20 million mined coins, leaving less than one million BTC left to be issued under its fixed supply cap.Summary
Bitcoin recently crossed the milestone of 20 million mined coins, meaning fewer than one million BTC remain to be issued before hitting the 21 million supply cap. This event occurred at block height 939,999, mined by the Foundry USA pool. The remaining supply will be distributed gradually over the next 114 years as block rewards continue to halve every four years. Since its inception in 2009, the block reward has decreased, most recently halving on April 20, 2024, to 3.125 BTC per block, slowing daily issuance to about 450 BTC. While miners earn transaction fees as a secondary revenue source, analysts note that the effectively available supply for trading might be significantly lower than the total mined amount due to an estimated three to four million lost coins and about 230 BTC that are permanently unspendable.
