CEX vs DEX 101: The difference between centralized and decentralized platforms for trading cryptocurrencies
🏦 CEX – Centralized Exchange
Definition:
A trading platform managed by a company or central authority, such as Binance, Coinbase, Kraken.

The platform holds the private keys to your wallet.

❌ Prone to security breaches
❌ Often requires identity verification (KYC)
❌ Subject to government regulation and may be shut down
🌐 DEX – Decentralized Exchange
Definition:
A trading platform that operates without a broker or central authority, relying on smart contracts (e.g., Uniswap, PancakeSwap, dYdX).
How it works:
No entity controls the platform.
Connects directly to your wallet (like MetaMask).
Trades are executed through smart contracts on the blockchain.
Advantages:
✅ Full control over your funds (you hold your private keys)
✅ High privacy, usually does not require identity verification
✅ Cannot be easily shut down (decentralized)
Disadvantages:
❌ Less user-friendly for beginners
❌ Lower liquidity compared to some centralized platforms
❌ Limited or no technical support
❌ Trade execution is slower and sometimes more expensive (depending on the network)
📌 Summary:
Choose CEX if you are a beginner and need an easy interface and technical support.
Choose DEX if you prefer privacy and full control over your funds.
