Things Worth Knowing
The Satoshi
1 BTC = 100,000,000 satoshis — the smallest unit, named after Bitcoin's creator. There are more sats in a single Bitcoin than cents in $10 million.

Pizza Day
On May 22, 2010, Laszlo Hanyecz paid 10,000 BTC for two Papa John's pizzas. It was the first real-world Bitcoin transaction.

21 Million — No More, Ever
Bitcoin's code caps the total supply at exactly 21,000,000. No central bank, no CEO, no government can print more. The last Bitcoin will be mined around the year 2140.

Lost Forever
An estimated 3–4 million Bitcoin are permanently lost — forgotten passwords, discarded hard drives, sent to unrecoverable addresses. They still count toward the 21 million cap, making the real supply even scarcer.

The Genesis Message
Satoshi embedded a newspaper headline in Bitcoin's very first block: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." A timestamp — and perhaps a statement.

Every 10 Minutes
A new Bitcoin block is mined roughly every 10 minutes — 24/7, 365 days a year. No holidays, no maintenance windows, no lunch breaks. The network has been running non-stop since January 3, 2009.

No CEO, No Office
Bitcoin has no company behind it, no headquarters, no board of directors, and no customer support. It runs on code maintained by hundreds of open-source contributors across the world.

Energy → Security
Bitcoin miners collectively use more energy than some countries — and that's the point. That energy is what makes the network practically impossible to attack. It's not waste, it's a wall.
