🔹 Will Bitcoin mining stop after the last 6.25 coins?
No, Bitcoin mining will not stop even after the last few unmined coins (including the last full BTC) are mined.
🔹 Why are there “only six unmined coins left”?
This sounds like a misunderstanding. As of July 2025:
About 19.7 million Bitcoins have been mined.
The total cap is 21 million.
That means there are still around 1.3 million BTC left to be mined.
The final Bitcoin will likely be mined around the year 2140 due to the halving schedule (mining rewards halve every ~4 years).
So, there are far more than 6 BTC left to be mined.
🔹 Will the 21 million limit ever increase?
No, unless Bitcoin's core rules are changed. But that’s extremely unlikely.
Bitcoin’s hard cap of 21 million is built into its code.
Changing it would require consensus from a large majority of the Bitcoin community (miners, developers, nodes, etc.).
This is technically possible, but it would break trust in Bitcoin’s fixed supply — its most important feature.
🔹 What happens after all BTC is mined?
Once all 21 million BTC are mined (around 2140):
Miners will earn only transaction fees.
If Bitcoin is widely adopted, fees could be enough to incentivize mining and secure the network.
✅ Summary:
No, Bitcoin mining won’t stop soon.
The 21 million cap still has ~1.3 million BTC to be mined.
That cap is very unlikely to increase.
Mining will continue with transaction fees after the last BTC is mined.
