Custody You deposit funds into the exchange (they hold your crypto) You keep control of your funds via your wallet

Ease of Use User-friendly, beginner-friendly, often includes customer support Requires some crypto knowledge, wallet setup

Speed & Fees Fast execution, often lower fees May be slower (depends on blockchain), network fees apply

Privacy/KYC Requires KYC (ID verification) Often no KYC required

Security Risks Prone to hacks (if exchange is compromised) Safer from central point-of-failure, but smart contract bugs are a risk

Liquidity Usually high (lots of buyers/sellers) Varies by token; sometimes lower liquidity
