As of March 9, fewer than 1 million bitcoins remain to be mined.
To date, more than 95% of Bitcoin’s maximum supply of 21 million BTC has already entered circulation. At the same time, the Bitcoin network continues to operate according to its predefined issuance schedule: miners add around 144 blocks per day on average, and mining difficulty is adjusted every 2,016 blocks, or roughly once every two weeks.
The block reward is cut in half every 210,000 blocks, with a Bitcoin halving taking place approximately once every four years. Following the halving event in April 2024, the reward per mined block dropped to 3.125 BTC, marking a new issuance era for the network. The next halving is expected around April–May 2028, when the block reward will decrease again to 1.5625 BTC.
The remaining bitcoins are expected to be mined gradually until around 2140.
