DEX vs CEX: Decentralized vs Centralized Exchanges

Bottom line: company-run vs code-run

There are two kinds of crypto exchange. A CEX (centralized exchange) is run by a company. A DEX (decentralized exchange) runs on smart contracts, letting wallets trade directly.

Key takeaways

CEX = company-managed (easy, support, KYC). DEX = no middleman (free but self-custody and self-responsibility). Beginners usually start with a CEX.
