Exchange custody simplifies access
A centralized exchange can make buying, selling, and reporting easier. It may provide account recovery, customer support, fiat rails, and tax exports. For many readers, that convenience matters.
The tradeoff is platform risk. Withdrawals can be delayed, accounts can be frozen, platforms can suffer failures, and users depend on the exchange's controls. The reader owns a claim inside the platform system, not the private keys themselves.
Self-custody shifts responsibility to the user
Self-custody means the user controls the keys needed to move assets. That can reduce platform dependence and give direct access to on-chain systems. It also removes many safety nets.
A lost seed phrase, wrong network transfer, malicious approval, fake wallet app, or compromised computer can become permanent loss. Self-custody is powerful only when the operational process is strong.
Operational controls lower both risk types
Exchange users can reduce risk with hardware security keys, strong two-factor authentication, withdrawal allowlists, unique passwords, and regular account checks. They can also avoid keeping more on an exchange than they need for near-term activity.
Self-custody users can reduce risk with hardware wallets, offline backups, small test transfers, separate hot and cold wallets, permission reviews, and written recovery plans. The goal is to make mistakes less likely before stress arrives.
The right answer may be a split
Many readers use both approaches. Trading balances may stay on exchanges while longer-term holdings move to cold storage. DeFi activity may use a separate hot wallet so experimental approvals do not touch core holdings.
Custody decisions should match asset size, activity level, technical comfort, recovery needs, and threat model. A simple plan that the reader can execute correctly is better than an advanced plan they cannot maintain.
