CEX vs DEX: What Is Right for You
What a CEX is
A centralised exchange (like Binance, Coinbase or Kraken) is a custodial platform: you deposit funds, the exchange holds them, and you trade against its order book. It typically requires KYC, offers fiat on-ramps, and is usually licensed by at least one regulator.
What a DEX is
A decentralised exchange (like Uniswap or Jupiter) lets you trade directly from your own self-custody wallet via smart contracts, without a company holding your funds. Most DEXs don't require KYC and can't freeze your account, but you're fully responsible for wallet security and transaction fees (gas).
Custody and risk trade-offs
A CEX concentrates custody risk in the platform — if it's hacked, mismanaged or insolvent, your funds are at risk regardless of your own security practices. A DEX shifts that risk to you: smart-contract bugs, phishing and seed-phrase theft are the main threats, not exchange insolvency.
Fees, speed and asset availability
CEXs generally offer lower, more predictable fees and instant fiat conversion. DEXs charge network gas fees that vary with blockchain congestion, but list new tokens far faster — often before any CEX does — and support far more long-tail assets.
Which should you use?
Most users benefit from both: a regulated CEX for fiat on/off-ramps and larger holdings, and a DEX for accessing DeFi, new tokens, or trading without KYC. Compare specific platforms on our exchange rankings and DeFi best-of guide.
