#CEXvsDEX101 : Centralized vs Decentralized Exchanges – What’s the Difference?

If you’ve spent any time in crypto, you’ve probably heard the terms CEX and DEX. But what do they really mean—and which one is better?

Let’s break it down. 👇

---

🏦 CEX: Centralized Exchange

Examples: Binance, Coinbase, Kraken

How it works: A centralized entity manages the platform, facilitates trades, holds custody of user funds, and ensures security.

🔑 Key Features:

User-Friendly: Easy UI, ideal for beginners

High Liquidity: Faster order execution and tighter spreads

Advanced Tools: Margin, futures, staking, etc.

Custodial: Your crypto is held by the platform

🚨 Watch Out For:

Requires KYC/AML

Relies on the exchange’s trustworthiness

Central point of failure (hacks, outages)

🌐 DEX: Decentralized Exchange

Examples: Uniswap, PancakeSwap, dYdX

How it works: Trades happen directly between users via smart contracts. You always keep control of your private keys.

🔑 Key Features:

Non-Custodial: You control your funds

Permissionless: No KYC, open to anyone

Transparent: On-chain trading with verifiable code

Token Variety: Access to smaller, newer projects

🚨 Watch Out For:

Slower transactions, especially on congested chains

Higher gas fees

Rug pulls and fake tokens if not careful
