What Happened?
Exactly four years after the Genesis Block, Bitcoin reached block 210,000. At that moment, the mining reward automatically halved from 50 BTC to 25 BTC per block, as written in Satoshi’s original code.
This was the first time the world saw Bitcoin’s built-in scarcity mechanism in action.
“The halving is Bitcoin’s most important economic event.”
At the time, Bitcoin traded around $12. Many miners quit, but the reduced supply eventually helped fuel the 2013 bull run.
Key Facts
Why It Mattered
This halving proved that Bitcoin’s monetary policy was real and predictable. It showed the world that supply would be reduced over time — something no fiat currency can promise.
The event planted the seeds for “HODL” culture and the powerful idea that Bitcoin is digital gold with a fixed, immutable supply.
