18 years ago, someone we still don't know sent a 9-page paper to a cryptography mailing list and quietly changed the rules of money.

October 31, 2008. Satoshi Nakamoto. "Bitcoin: A Peer-to-Peer Electronic Cash System."

Two months later, the first block got mined with a London Times headline embedded in it — banks on the brink of a second bailout. A few days after that, 10 $BTC moved from Satoshi to Hal Finney. The first real transaction.

By 2010, someone traded 10,000 $BTC for two pizzas. That actually happened.

Then Satoshi disappeared. Last forum post in December 2010. Final email in April 2011: "moved on to other things."

What happened next:

1. Four halvings survived
2. El Salvador made it legal tender
3. Wall Street launched spot ETFs
4. US government created a Strategic Bitcoin Reserve
5. October 2025: all-time high of $126,198

No founder. No CEO. No company. Just code, consensus, and 18 years of proving that decentralized money can work.

Happy birthday, $BTC. 🎂
