Bitcoin's Mined Supply Surpasses 20 Million as Loss Estimates Mount
Binance founder Changpeng Zhao (CZ) has highlighted the finite nature of Bitcoin's supply, stating that over 20.07 million BTC have been mined as of August 2026.
This represents approximately 95.6% of Bitcoin's maximum supply of 21 million coins, with only 4.4% remaining to be mined.
CZ also estimated that between 10% and 20% of existing BTC is lost or inaccessible due to forgotten private keys, hardware failures, or other mishaps.
This would leave the effective circulating supply between 16.06 million and 18.06 million BTC, making Bitcoin even scarcer than its nominal supply suggests.
