The 20 Millionth Bitcoin: A Historic Milestone
On March 9, 2026, at block 940,000, the 20 millionth Bitcoin was mined. It’s a milestone worth understanding.
What It Means
Bitcoin has a hard cap of 21 million coins. No more will ever be created. With 20 million now in existence, 95.24% of all Bitcoin that will ever exist has already been mined.
The remaining ~1 million Bitcoin will be created slowly over the next century, with the mining reward halving approximately every four years until the last satoshi is mined around the year 2140.
The Numbers
- Total supply cap: 21,000,000 BTC
- Mined as of March 9, 2026: 20,000,000 BTC
- Remaining: ~1,000,000 BTC
- Network hashrate: Over 1 Zettahash — the most secure computing network in human history
- Mining cost: Approximately $137,000 per Bitcoin at the time of the milestone
Why It Matters
In a world of unlimited money printing and persistent inflation, Bitcoin’s fixed supply is revolutionary. No government, no central bank, no corporation can create more Bitcoin. The rules are set in code and enforced by a global network of miners and nodes.
The 20 million milestone is a reminder that scarcity isn’t just a feature of Bitcoin — it’s the foundation of its value proposition as sound money.
What Comes Next
As the remaining supply dwindles, Bitcoin’s scarcity becomes increasingly real. The next halving will reduce the mining reward further, making each new Bitcoin more costly to produce.
For those who understand what this means, it’s a turning point. For those who don’t — that’s exactly why the Proof of Work Foundation exists.
Understanding Bitcoin starts with understanding scarcity. And scarcity just got very real.
