Centralized Exchanges (CEXs) are like traditional banks for crypto, offering ease of use, high liquidity, and fiat-to-crypto conversions, but you entrust your funds to them. Decentralized Exchanges (DEXs), on the other hand, let you trade directly from your own wallet, offering greater control, privacy, and access to new tokens, but they can be more complex to use. Your choice depends on your priorities: CEXs for convenience and ease, DEXs for self-custody and privacy.
