Why this topic matters
A centralized exchange operates accounts, order books, and custody, while a decentralized exchange uses a wallet and smart contracts with more direct user control over keys and approvals.
A practical review order
A CEX can be convenient and fast, but users rely on withdrawal policy, operations, custody, and counterparty controls. A DEX can offer on-chain transparency and permissionless access, while contract, liquidity, slippage, and approval risks remain.
Common mistakes to avoid
Check supported networks, assets, fees, withdrawals, pricing, protection, and incident response. With a DEX, verify the official URL and contract address and review approval scope.
Key takeaway
Neither structure is automatically safer in every situation. Compare trading risk and custody risk separately and choose based on the use case and control you can manage.
