Bitcoin Mining Exceeds 20.07 Million, Remaining Supply at 4.4%

As of August 2026, the amount of Bitcoin (BTC) mined has surpassed 20.07 million, with approximately 4.4% of the supply remaining. Changpeng Zhao (CZ), founder of Binance, stated on social media, "As of August 2026, more than 20.07 million Bitcoins have been mined, and only about 4.4% of the supply is waiting to be mined." He explained that "it is estimated that 10-20% of existing Bitcoins are lost, locked, or unrecoverable," adding that "Bitcoin is a deflationary asset." The total issuance of Bitcoin is capped at 21 million, and mining rewards are periodically reduced according to a halving design. This categorizes Bitcoin as an asset with a gradually decreasing new supply rate. Zhao's comments are interpreted as focusing on the actual circulating supply rather than the total mined amount. If there are lost or inaccessible amounts, a discrepancy can arise between the nominal supply and the supply available in the market. However, the estimate of 10-20% loss is Zhao's personal estimate, and it is difficult to definitively ascertain the actual unrecoverable amount externally, as the accessibility of specific wallets cannot be directly verified within the Bitcoin network.
