Self-custody versus exchange: what changes if you lose access
The difference isn’t technical, it is about who holds the key. Everything else follows from that: whether there is support, whether there is a recovery procedure, whether anyone can freeze your funds, and whether losing a password is an inconvenience or a disaster.
The table
| Exchange | Self-custody wallet | |
|---|---|---|
| Who holds the key | The company | You |
| If you forget the password | A recovery procedure | No account recovery |
| If the company shuts down | Your money is at risk | It doesn’t affect you |
| If you lose the phrase | There is no phrase | You lose access |
| Can your funds be frozen | Yes | No |
| Is identification required | Yes | No |
| Who answers if something fails | The company | Nobody |
How to tell which you are in
If they asked for your ID at sign-up, if you logged in with a username and password from any device, if you could deposit euros from your bank: it is an exchange. If you were given twelve or twenty-four words at the start and there was no sign-up: it is a self-custody wallet. This is expanded in exchange versus your own wallet.
The real trade-off
There is no good option and bad option: there is a trade-off. On an exchange you delegate custody and gain a safety net: if you forget the password, there is a route back. In exchange, you depend on the company continuing to exist, continuing to operate and not freezing your account.
With a self-custody wallet you depend on nobody, and that is why there is nobody to turn to. The cost of that independence is exactly the problem that brought you here.
A third case worth naming
The exchange that shut down, went bankrupt or vanished with the money inside. That is neither a technical recovery nor a support matter: it is an insolvency procedure that can take years and rarely returns one hundred per cent. See why a closed exchange account cannot be recovered.
