CEX vs DEX 101: Beginner-Friendly Guide!
Understanding the difference between CEX (Centralized Exchange) and DEX (Decentralized Exchange) is crucial for anyone getting into crypto.
๐ฆ CEX (Centralized Exchange)
Examples: Binance, Coinbase, Kraken, KuCoin
โ Pros:
1. Easy to use (great for beginners)
2. High liquidity (easy to buy/sell)
3. Fast transactions
4. Customer support available
5. Often offers fiat on-ramp (buy with USD, EUR, etc.)
โ Cons:
1. You donโt control your private keys (โNot your keys, not your cryptoโ)
2. Can be hacked (since it's centralized)
3. Subject to regulations and KYC/AML laws
๐ DEX (Decentralized Exchange)
Examples: Uniswap, PancakeSwap, dYdX, SushiSwap
โ Pros:
1. You control your keys (true self-custody)
2. No KYC (mostly anonymous)
3. Permissionless (anyone can use)
4. More aligned with decentralization ethos
โ Cons:
1. Less beginner-friendly
2. Lower liquidity than CEXs (especially for small tokens)
3. Slower and more costly on some blockchains (e.g., Ethereum gas fees)
4. No centralized support if you make a mistake
๐ Key Difference: Custody
CEX: You deposit funds to the exchange. They hold the private keys.
DEX: You trade directly from your wallet. You hold the keys.
