Fixed maximum.
Unlike fiat currencies, Bitcoin's maximum monetary supply is defined by consensus rules rather than discretionary monetary policy.
21 million
Bitcoin supply,
made visible.
Bitcoin's issuance is transparent, predictable and ultimately finite. The protocol caps total supply at 21,000,000 BTC.

Why 21 million?
Bitcoin follows a predetermined issuance schedule. New BTC enters circulation as a block subsidy paid to miners, while periodic halvings reduce that subsidy over time. The result is an asymptotic approach toward the 21 million maximum.
Predictable schedule.
Each halving reduces the rate at which new Bitcoin enters circulation, pushing the issuance curve toward zero.
