Is It Safe to Keep Crypto on an Exchange? A Guide to Risks, Insurance, and Security

Is it safe to keep crypto on an exchange? Centralized exchanges provide convenient access to trading, liquidity, fiat deposits, withdrawals, and account recovery, but they also create custodial and counterparty risks. When cryptocurrency is stored on an exchange, the platform controls the private keys, meaning users depend on its security, liquidity, governance, and ability to process withdrawals. This guide compares exchange custody with self-custody and explains major risks, including hacks, insolvency, frozen withdrawals, phishing, regulatory action, weak asset segregation, and limited insurance coverage. It also examines proof of reserves, cold storage, security controls, and the limits of exchange protection funds. For most users, keeping a small active trading balance on a reputable exchange may be practical, while large long-term holdings are generally better suited to hardware wallets, multi-signature storage, or other secure custody solutions. Strong passwords, app-based 2FA, withdrawal whitelists, test transactions, and diversified storage can further reduce risk.
