#CEXvsDEX101

main difference between a Centralized Exchange (CEX) and a Decentralized Exchange (DEX) comes down to how they are managed and how control is exercised over assets and trading operations.

🔹 Centralized Exchange (CEX)

✅ Pros:

User-friendly: Easier to use, especially for beginners.

High liquidity: More buyers and sellers = faster trades.

Advanced features: Margin trading, derivatives, stop-loss, etc.

Customer support: Help available if you lose access or need help.

❌ Cons:

Custodial: The exchange controls your private keys.

Security risk: Vulnerable to hacks (e.g., Mt. Gox, FTX).

Regulation: Subject to government control and KYC/AML requirements.

Downtime: Can go offline due to maintenance or shutdowns.

Examples:

Binance, Coinbase, Kraken, KuCoin.

🔹 Decentralized Exchange (DEX)

✅ Pros:

Non-custodial: You control your funds and keys at all times.

Privacy: Typically no KYC (though this is changing in some jurisdictions).

Permissionless: Anyone can use it; no account required.

Resistant to censorship: No central authority to shut it down.

❌ Cons:

Lower liquidity: Especially for smaller tokens.

Complex UI: Can be confusing for beginners.

Slippage and MEV: Trades can be front-run or incur high slippage.

Limited support: No customer service if something goes wrong.

Examples:

Uniswap, PancakeSwap, SushiSwap, Curve, dYdX
