Exchanges Are Not Wallets

There’s a confusion that trips up a lot of new Bitcoin holders.

When you buy Bitcoin on an exchange, it shows up in your exchange account. It has a balance. It feels like it’s yours. It looks like a wallet.

It isn’t.

What you have on an exchange is an IOU. The exchange holds the actual Bitcoin. What you hold is a claim against their balance sheet — a promise that they’ll give it to you when you ask. That promise is only as good as the exchange itself.

A Bitcoin wallet is different. A real wallet gives you direct ownership of the Bitcoin — secured by a private key that only you hold. No company. No intermediary. No promise required.

Think of it like the difference between storing cash in a bank and storing it in a safe in your home. The bank holds your money and promises to give it back. The safe holds it directly, under your control, with no third party involved.

Neither is perfect. The bank offers convenience and insurance. The safe offers direct ownership but requires you to take responsibility for security.

With Bitcoin, the equivalent of the safe is a self-custodial wallet. The rest of this week covers what that means and how it works.

For now, the key idea: an exchange account is a starting point, not a destination. Most long-term Bitcoin holders move their coins off exchanges once they understand how wallets work.

That understanding starts tomorrow.

Tomorrow: Day 70 first — then wallets.
