Scarcity: Why 21 Million?

We understand why the fixed supply is the core of Bitcoin's value.

More paper currency can be printed at any time — and with every increase, the value of what you hold falls. That isn't a flaw; it's how it works.

With Bitcoin, the number is written into the rules: 21 million, never more. No government or company can change it.

And this scarcity isn't a promise on paper — anyone can verify it themselves, at any moment, through the network.

When supply is fixed and can't be manipulated, money becomes an honest measure of value over time. This is where the real difference begins.

In the next station, we'll see how to hold this money yourself — not in someone else's hands.
