Why Bitcoin’s Supply Is Capped at 21 Million Forever

bitcoin’s 21 million supply cap is hard‑coded in its protocol, enforced by halving events and network consensus, ensuring predictable scarcity and preventing inflation.
bitcoin’s first halving in November 2012 cut the block reward from 50 to 25 BTC. This programmed event reduced new supply, tested network security, and set a precedent for future halvings.
bitcoin’s 21 million coin limit is enforced by code and a halving schedule. This article explains how new coins are issued, when they’ll run out, and why the cap matters.
bitcoin’s four-year halving cycle reduces the block reward by 50%, slowing new supply. This programmed scarcity often influences market sentiment, miner behavior, and long-term price dynamics.
bitcoin’s fixed 21 million supply cap creates a structurally deflationary framework, contrasting with inflationary fiat currencies whose supply expands through central bank policy.
