#CEXvsDEX101 CEX vs DEX 101: A Beginner’s Guide
Understanding the difference between Centralized Exchanges (CEXs) and Decentralized Exchanges (DEXs) is fundamental if you're getting into cryptocurrency. Here's a breakdown of the basics:
---
🔵 What is a CEX (Centralized Exchange)?
A CEX is a platform operated by a company that facilitates crypto trading. Users deposit funds into the exchange, and it manages trading and custody on your behalf.
Examples: Binance, Coinbase, Kraken, KuCoin
Pros:
✅ Easy to use (especially for beginners)
✅ High liquidity and fast transactions
✅ Fiat on-ramps (buy with credit card, bank transfer)
✅ Customer support available
Cons:
❌ You don’t hold your private keys ("Not your keys, not your crypto")
❌ Subject to hacks and regulatory scrutiny
❌ KYC/AML requirements
---
🟣 What is a DEX (Decentralized Exchange)?
A DEX is a peer-to-peer marketplace where users trade directly from their wallets, without giving custody to a third party.
Examples: Uniswap, PancakeSwap, SushiSwap, dYdX
Pros:
✅ You control your funds (non-custodial)
✅ No sign-up or KYC needed
✅ Open and transparent (runs on smart contracts)
✅ Access to a wider variety of tokens
Cons:
❌ Less beginner-friendly
❌ Slower or more expensive transactions (depending on network)
❌ Risk of impermanent loss and rug pulls
❌ Limited fiat integration
