Centralized vs. Decentralized Exchanges: What's the Difference?
Centralized exchanges (CEXs)
Platforms like Coinbase, Kraken, and Binance act as a middleman: you deposit funds, they hold them in custody, and you trade through their internal system. They offer fiat on-ramps (bank/card deposits), customer support, and simpler interfaces — ideal for beginners.
Decentralized exchanges (DEXs)
Platforms like Uniswap or Curve let you trade directly from your own wallet using smart contracts, with no company holding your funds. You always retain custody, but you also lose the safety net of customer support if you make a mistake — there's no one to call.
- DEXs typically only support crypto-to-crypto trades, not direct bank/card purchases.NOTE
- Smart contract bugs or fake token listings are DEX-specific risks; always verify contract addresses.CAUTION
Which should you use?
Start on a centralized exchange to buy your first crypto with a bank account or card. Once you're comfortable with wallets and gas fees, decentralized exchanges open up access to a much wider range of tokens and DeFi tools.
