What Is a Bitcoin Hard Cap?

[etfs]

Did you know? Bitcoin has a hard cap of 21 million coins. This is the maximum number of BTC that will ever exist, baked into its code by Satoshi Nakamoto.

Why it matters:

Ensures scarcity, boosting value as demand grows.

Guarantees predictable monetary policy with halving events every 4 years.

Protects decentralization—no central authority can print more.

Over 19.8M BTC have already been mined, leaving less than 1.2M coins to come. That’s why Bitcoin is often called digital gold.
