#CEXvsDEX101 #CEXvsDEX101: A Beginner’s Guide to Centralized vs. Decentralized Exchanges

Let’s break it down simply:

🔹 What is a CEX (Centralized Exchange)?

Think: Binance, Coinbase, Kraken

Key Traits:

Owned by a company that controls operations.

Users deposit funds into the exchange's wallets.

Trades are handled off-chain (faster, lower fees).

KYC/AML usually required (identity verification).

Often offers better liquidity and customer support.

Pros:

User-friendly for beginners.

Fast transactions.

High liquidity and trading volume.

Cons:

Users don’t control their private keys.

Prone to hacks and regulations.

Potential for withdrawal freezes or policy changes.

🔸 What is a DEX (Decentralized Exchange)?

Think: Uniswap, PancakeSwap, dYdX

Key Traits:

Operates via smart contracts on blockchain.

No middleman – peer-to-peer trading.

Users trade directly from their wallets.

Usually no KYC, more anonymous.

Pros:

You control your funds (not your keys, not your crypto!).

Censorship-resistant.

Permissionless and often open-source.

Cons:

Slower transactions, especially during high network activity.

Can be complex for beginners.

Lower liquidity for smaller tokens.

Limited customer support.

🧠 Final Thoughts:

Use CEX if you’re new, want fiat on-ramps, or need fast trades.

Use DEX if you value privacy, self-custody, and decentralization.

Many advanced users use both depending on the situation.
