Overview
Circulating Supply is the total number of Bitcoin that have ever been mined. New coins enter circulation with each block as miners receive the block subsidy reward.
Formula
Interpretation
- Grows with every new block (~every 10 minutes).
- Growth rate halves every ~210,000 blocks (roughly every 4 years) due to Bitcoin halvings.
- Hard-capped at 21 million BTC.
Use Cases
- Per-coin metrics: Denominator for Realized Price (Realized Cap ÷ Circulating Supply).
- Inflation tracking: Monitor the rate of new supply issuance.
- Scarcity analysis: Compare current supply to the 21M cap.
