Day 31Part 2: What Bitcoin Is

Bitcoin in One Sentence

Here it is:

Bitcoin is digital money that no government, bank, or company controls — with a fixed supply that nobody can change.

That’s it. Every other detail — the technology, the wallets, the price — is just elaboration on those two ideas.

But let’s slow down on those two ideas, because they’re each doing a lot of work.

“No government, bank, or company controls it” means there is no headquarters to raid, no CEO to arrest, no server to shut down. Bitcoin runs on thousands of computers around the world simultaneously. To stop it, you’d have to stop all of them at the same time. Nobody has managed that in 15 years of trying.

“A fixed supply that nobody can change” means there will only ever be 21 million Bitcoin. Not 22 million. Not 21 million and one more if a government needs extra money. The number is set in the code, enforced by the network, and has never changed since the day Bitcoin launched.

Think about what those two things together mean for your money. Every currency you’ve ever used can be created in unlimited quantities by someone else’s decision. Bitcoin cannot. Every financial system you’ve ever used has a central point of control. Bitcoin does not.

This isn’t a technical curiosity. It’s a fundamentally different idea about what money can be.

The next 29 days unpack exactly how and why it works.

Tomorrow: what “digital cash” actually means — and why it’s nothing like PayPal.
