Over 95% of Bitcoin's 21 million supply has now been mined

Bitcoin's total supply has now surpassed 20 million coins in circulation. This milestone signifies that over 95% of the 21 million that will ever exist have already been mined. However, the amount actually available for use is significantly lower due to lost and unclaimed coins.

As of early 2026, miners are adding approximately 450 new Bitcoin to the supply each day. Each newly confirmed block releases 3.125 BTC, maintaining the current inflation rate at about 0.82% per year. By the next halving in 2028, this rate will decrease to around 0.4%.

Less than 1 million Bitcoin remain to be mined, representing just 4.76% of the total supply. Once all coins are issued, no new Bitcoin will enter circulation. Nevertheless, the usable supply is considerably smaller than the theoretical maximum.

Estimates suggest 3 to 4 million BTC are lost forever, locked away by forgotten keys, early adopter errors, or unrecoverable wallets. Historical losses include Satoshi Nakamoto's estimated 1 million lost coins, along with others lost to hacks, deceased owners, or intentionally burned addresses. These factors reduce the practical supply to around 14–15 million BTC.

As mining approaches its final phase, Bitcoin's inflation will soon drop below 0.5%. The disparity between mined coins and those actually in use underscores the impact of lost and unclaimed Bitcoin. As the network matures, the remaining supply will continue to shrink until issuance ceases entirely.
