Basics: What Is Bitcoin?

We start from zero: what Bitcoin really is — and why it's unlike anything you've known about money.

Bitcoin is digital money with no bank or company behind it. No one owns or controls it alone; it runs on a worldwide network of computers that all agree on the same rules.

What sets it apart: the supply is fixed — 21 million, no more. No one can simply print more, the way paper currencies work. This is where the real difference lies.

And most importantly: when you hold Bitcoin with your own keys, it truly belongs to you — not as a promise from an institution that could fail or shut down.

Bitcoin isn't a company or an app, but a set of rules no one can change on their own. This is where the real idea of sovereignty over your money begins.

In the next station, we'll see why scarcity is the foundation of everything.
