CZ: Over 20.07 Million Bitcoin Mined, Actual Circulating Supply Likely Lower

BitcoinWorld CZ: Over 20.07 Million Bitcoin Mined, Actual Circulating Supply Likely Lower Binance founder Changpeng Zhao (CZ) said on X that Bitcoin’s cumulative mined supply has surpassed 20.07 million as of August 2026, reaching 95.6% of its maximum supply of 21 million.

Zhao noted that only 4.4% of the total supply remains to be mined, and he estimated that 10% to 20% of existing BTC has been lost or is inaccessible, leaving those tokens permanently unrecoverable. He described Bitcoin as a deflationary asset.

Context and Implications for Bitcoin’s Supply Bitcoin’s supply schedule is encoded in its protocol, with block rewards halving approximately every four years. The last bitcoin is expected to be mined around the year 2140.

As of now, over 95% of all bitcoin that will ever exist has been mined, underscoring the scarcity that underpins its value proposition.
