A Historic Moment: The 20 Millionth Bitcoin Has Just Been Mined
Tonight marks a defining milestone for the Bitcoin network — the 20 millionth coin is expected to be unlocked at block height 940,000. This event not only highlights the progress of decentralized currency adoption but also signals the rapid approach of mining's final era.
Over 95% of Supply Now in Circulation
Chain data confirms that 95.2% of Bitcoin’s 21 million cap has already entered circulation. Just 1 million coins remain to be mined, to be distributed over the next 114 years. The scarcity engine is now running at its slowest pace yet.
How Halving Built Digital Scarcity
Bitcoin’s value proposition hinges on its deflationary design. Every 210,000 blocks, the block reward halves:
- Genesis reward: 50 BTC
- First halving: 25 BTC
- Second: 12.5 BTC
- Third: 6.25 BTC
- Next: 3.125 BTC
This built-in mechanism ensures diminishing issuance, mirroring digital gold’s scarcity.
The Final Million: A Century-Long Race
At current block speeds — one every 10 minutes — the last 1 million BTC will take until 2138 to be fully mined. As rewards shrink, miners will increasingly rely on transaction fees for sustainability.
With 20 million coins now in play, the focus shifts from mining profits to long-term holding, network security, and real-world utility — ushering in a mature phase of decentralized finance.
