Custodial vs self-custody
Either a company holds your bitcoin for you, or your keys do. Everything follows from that.
In plain words
Custodial: a company holds the keys and owes you bitcoin. You hold a login and a promise. Self-custody: your wallet holds the keys, and the coins answer to you alone. Custody feels easy — password resets, support desks — and rests on the company staying honest, secure, and solvent. Self-custody trades comfort for ownership: no one can freeze your coins, and no one can undo your mistakes. Those are the same fact.
Why it matters
- Exchange disasters — hacks, freezes, bankruptcies — fall on custodial users.
- Self-custody is Bitcoin as designed. Custody re-installs the middleman.
- An honest answer can be "some of each" while you learn.
Not to be confused with
- Hot vs cold — that's where keys live; this is who has them.
