Bitcoin cannot exceed 21 million coins because its issuance schedule shrinks over time and network nodes reject blocks that break the rules.

How is bitcoin limited to 21 million? The cap comes from code-based issuance: new BTC enters through block rewards that keep getting cut in half.

The 21 million cap is fixed, but new bitcoin enters slowly. What is left depends on issuance progress, halvings, and circulating supply.

Bitcoin cannot simply go past 21 million. The cap is part of the protocol; unit splits, forks, and platform balances do not change BTC supply.

Bitcoin is capped at 21 million because its issuance schedule was built to be scarce, predictable, and resistant to arbitrary expansion.
