History Made: Bitcoin's 20 Millionth Coin Is Mined — Only 1 Million Left to Ever Exist
On March 9, 2026, the Bitcoin network reached a milestone that
no monetary system in history has ever achieved: the mining of its
20 millionth coin. Since the Genesis block was
mined by Satoshi Nakamoto in January 2009, it took exactly 17 years, 2 months,
and one week for the network to reach this landmark. Now, just
1 million Bitcoin remain — and they will take over a century to release.
The Historic Milestone: Key Facts
| Detail | Data |
|---|---|
| Date of 20 Millionth BTC | March 9, 2026 |
| Block Height | 939,999 |
| Mining Pool | Foundry USA |
| Block Reward Received | 3.125 BTC |
| % of Total Supply Now Mined | 95.24% |
| Remaining Supply | < 1 Million BTC |
| Time to Mine First 20M BTC | 17 years |
| Time to Mine Last 1M BTC | ~114 years (until ~2140) |
What Does "Only 1 Million Left" Actually Mean?
The 20 million mark means 95.24% of all Bitcoin that will
ever exist is now out in the world. For every 20 coins already mined, just one
remains to be created. The remaining 1 million will take about 114 years to fully issue.
But the real supply shock is even bigger. Research from
Chainalysis and River Financial estimates that between 2.3 million and 3.7 million BTC
are permanently inaccessible due to lost private keys, forgotten passwords, deceased
holders, and coins sent to unspendable addresses. This means the
effective circulating supply could already be lower than 17 million BTC.
Bitcoin Supply Timeline: What Comes Next
| Year | BTC Mined | % of Total Supply | Daily Issuance |
|---|---|---|---|
| 2026 (Now) | 20,000,000 | 95.24% | ~450 BTC/day |
| 2028 (Next Halving) | ~20,400,000 | ~97% | ~225 BTC/day |
| 2032 (Halving) | ~20,600,000 | ~98% | ~112 BTC/day |
| 2035 | ~20,790,000 | 99% | <30 BTC/day |
| 2060s | ~20,950,000 | ~99.75% | <2 BTC/day |
| ~2140 | 20,999,999.97 | 100% (final satoshi) | 0 BTC/day |
Next Bitcoin Halving: April 2028
Miners currently receive 3.125 newly minted BTC per block
following the most recent halving on April 20, 2024, along with transaction fees.
The next Bitcoin halving is scheduled for April 11, 2028, when the block reward
will drop to 1.5625 BTC.
What Happens to Miners After All Bitcoin Is Mined?
Many publicly traded miners are expected to exit Bitcoin
mining in 2027 and 2028, liquidating Bitcoin holdings to fund pivots into AI and
high-performance computing workloads. Once all BTC is mined around 2140,
miners will earn revenue exclusively from transaction fees paid by users — a model
already baked into Bitcoin's protocol design.
Why This Matters: Bitcoin's "Hard Money" Argument
This milestone reinforces how the economics of Bitcoin are
different from traditional currency systems like the dollar, which allow governments
to always print more money.
- 📉 No inflation — Bitcoin's annual inflation rate is now below 1% and falling
- 🔒 Predictable supply — every future coin is scheduled in code, unalterable
- 🌍 Global scarcity — only 21M BTC for 8 billion people — ever
- 💎 Lost coins = permanent scarcity — 2.3–3.7M BTC gone forever
How Is Bitcoin's Price Reacting?
U.S. spot Bitcoin ETFs recorded roughly $4.5 billion in net
outflows year-to-date, including a five-week withdrawal streak, as institutional
investors reduced exposure during a risk-off period. Bitcoin is currently
trading around $70,654, down significantly from its all-time high
of $126,080 reached in October 2025 — suggesting the market has
not yet fully priced in the scarcity milestone.
