Custody is just the question of who holds the keys to your crypto. Get this one concept and most of the security advice, and most of the product choices, fall into place.
There is no universally right answer. There is the answer that fits how you want to operate and how much responsibility you want to carry.

It is about keys, not coins
Crypto is controlled by a secret key, usually backed up as a seed phrase, a list of words. Whoever holds that key controls the money. So the real question is not where the coins are, but who holds the key that moves them.
The seed phrase is the money. Guard it like cash, because anyone who has it can spend your funds.
The two models
- Custodial (a processor holds the keys): like a bank account. Easy, recoverable, but you rely on the company and its terms.
- Self-custody (you hold the keys): like cash in your own safe. Full control and no middleman, but no one to call if you lose the key.
The custodial vs. non-custodial comparison lays both out side by side.
How to choose
If you want crypto to behave like any other payment, and you would rather not think about keys, a custodial processor that converts to dollars is the low-friction path. If independence from any company matters to you and you will follow a simple backup routine, self-custody is well within reach.
Many businesses blend the two: a processor for daily settlement, and a self-custody wallet for any crypto they choose to keep.
Common questions
- Is self-custody only for technical people?
- No. A basic routine, writing down the seed phrase and storing it offline, is enough for most small businesses.
- Is a processor safer than self-custody?
- It removes the risk of losing your own keys, but it adds dependence on a company that could freeze or delay funds. Each trades one risk for another.
