How Many Bitcoins Are Left? ⏳

What happens when 100% of Bitcoin is mined?
Once the full 21 million BTC are mined (estimated around the year 2140), no new bitcoins will be created. Miners will be compensated solely through transaction fees, as the block subsidy (new coin issuance) will drop to zero. While the maximum supply will be fixed at 21 million BTC, the actual circulating supply will gradually decline over time due to lost or inaccessible coins.
