Let’s talk about centralized and decentralized exchanges.
On a CEX, on-chain transactions usually occur only when you deposit or withdraw funds; trades within the platform simply update the balances in its ledger.
One thing worth considering is that CEXs generally offer fiat on-ramps and off-ramps, customer support, and account recovery services—but using them means trusting the platform to keep your assets secure and manage them properly.
If you want convenient deposits and withdrawals plus customer support, a CEX may be a better fit. If you want to control your own private keys and use on-chain apps, you’ll need to learn how to keep your wallet secure.
