CEX vs DEX for Trading
When to use centralized vs decentralized exchange — practical comparisons.
Centralized and decentralized exchanges have different advantages — an experienced trader knows when to use what.
CEX (Binance, OKX, Kraken):
Advantages:
•High liquidity — small spread, large order book
•Fiat integration (EUR/RSD on-ramp)
•User interface (familiar to beginners)
•Futures, options, margined trading
•Customer support
•Fiat off-ramp (withdrawal to bank account)
Disadvantages:
•Custodial — not your private keys
•KYC mandatory
•Regulatory risk (FTX, Mt. Gox)
•Geographic restrictions
•API limitations for high frequency
DEX (Uniswap, Jupiter, dYdX):
Advantages:
•Non-custodial — private keys yours
•No KYC
•Access to new tokens (before CEX listing)
•Airdrop eligibility (CEX users often excluded)
•On-chain transparency
Disadvantages:
•Less liquidity for niche pairs
•Gas costs (on Ethereum mainnet)
•Impermanent Loss for LP
•Slippage on small pools
•More complex UI
•No fiat integration
Practical strategy:
•CEX for: blue chip spot, futures, fiat on/off
•DEX for: new tokens, airdrop farming, self-custody DeFi
•Both: keep 20% on DEX/self-custody, 80% on CEX for trading
