Bitcoin’s supply is governed by immutable math rather than the shifting policies of central banks. The journey to 20 million BTC highlights the relentless precision of the protocol:
-
The Sprint: The first 20 million BTC were mined in approximately 6,267 days since the Genesis Block in 2009.
-
The Marathon: Due to the “halving” mechanism—which slashes the issuance of new coins every four years—the final ~1 million BTC will trickle out until the year 2140.
-
Current Issuance: At a block height of approximately 940,000, new supply inflows have become negligible compared to growing global demand.
Unlike fiat currencies, which can be printed at will, Bitcoin’s supply is inelastic. There is no marketing team, no CEO to adjust the rules, and no central authority to dilute the value of existing holders.
