Crypto Wallet vs Exchange: Where Is Crypto Held?

An exchange account and a self-custody wallet solve different problems. The central question is who controls the private keys and who is responsible for recovery.

When crypto stays on an exchange

The exchange typically controls the wallets and private keys while showing an account balance assigned to you. This can make trading, password recovery, and customer support more convenient.

The tradeoff is counterparty risk: withdrawals, access, or the provider itself can experience restrictions, outages, security incidents, or financial problems.

When crypto moves to self-custody

A self-custody wallet gives the user control of the keys needed to authorize transactions. It reduces dependence on an exchange but places security and recovery responsibilities on the user.

Anyone with the seed phrase or private key may control the assets. Losing the recovery information, sending to the wrong address or network, or approving a malicious transaction can lead to irreversible loss.

A decision framework for beginners

Consider why you hold the asset, how often you trade, the amount involved, your ability to secure recovery information, and whether you understand test transfers and network fees.

Self-custody is not automatically safer when used incorrectly, and exchange custody is not risk-free. Learn both risk models before moving funds.

If you withdraw, test a small amount first and prove you can restore access to the wallet backup before treating self-custody as solved.

Common questions

Frequently asked questions

Is a crypto wallet safer than an exchange?

It depends on the threats and the user's security practices. Self-custody removes some exchange risk but adds full key-management responsibility.

What happens if I lose a wallet seed phrase?

If you also lose access to the wallet and have no valid backup, the assets may be permanently inaccessible.

Should beginners withdraw crypto immediately?

Not automatically. First learn the wallet, backup, address, network, fee, and recovery process. A small test transfer may be appropriate.
