Bitcoin has officially mined its 20 millionth coin as of March 9, 2026, marking a historic milestone with over 95% of its total supply now in circulation. Only 1 million BTC remain to be mined, with final issuance expected by the year 2140.
🪙 Bitcoin Hits 20M Milestone – March 9, 2026
- Block Height: 939,999
- Mined By: Foundry USA mining pool
- Block Reward: 3.125 BTC (post-April 2024 halving)
- Total Supply Cap: 21 million BTC
- Circulating Supply: 95.24% mined
🔹 Why It Matters
- This milestone reflects Bitcoin’s engineered scarcity, a core feature of its deflationary design.
- With fewer than 1 million BTC left to mine, long-term supply pressure may intensify.
- The final BTC is expected to be mined around 2140, due to halving cycles every four years.
