CEX vs DEX: Core Differences
🏢Centralized Exchange (CEX)
Traditional trading platforms operated by companies, where users deposit funds to the exchange.
✅ Advantages:
- High liquidity, fast execution
- User-friendly interface for beginners
- Supports fiat deposits/withdrawals
- Comprehensive customer support
- Offers futures, leverage and advanced features
⚠️ Disadvantages:
- Funds held by platform, risk of hacks or exit scams
- Requires KYC verification
- May restrict users from certain regions
- Trading activity monitored by platform
🔗Decentralized Exchange (DEX)
Automated trading platforms based on smart contracts, users retain control of funds.
✅ Advantages:
- Full control of funds (non-custodial)
- No KYC required, anonymous trading
- Global access without restrictions
- Transparent, on-chain verifiable
- Trade any token including new launches
⚠️ Disadvantages:
- Lower liquidity, high slippage for large orders
- Requires paying blockchain gas fees
- Complex interface, steep learning curve
- No customer support, irreversible operations
- Smart contract risks and scam projects
💡 How to Choose?
For beginners and large traders, prioritize regulated CEX platforms (like Binance, OKX, Coinbase). Once comfortable, explore DEX to experience decentralized trading.
Golden Rule: "Not your keys, not your coins" - Only keep trading funds on CEX, store large amounts in cold wallets.

Frequently Asked Questions
Q1: Which is better: CEX or DEX?▼
CEX suits beginners and high-frequency traders: user-friendly interface, high liquidity, fast trading, fiat on/off-ramps. But requires trusting the exchange, with risks of hacks or insolvency. DEX suits experienced users: full asset control, more privacy, censorship-resistant, but lower liquidity, high gas fees, steeper learning curve. Recommendation: Start with CEX, explore DEX after gaining experience.
Q2: How to choose between Binance, OKX, and Coinbase?▼
Binance: World's largest exchange, best liquidity, most coin pairs, low fees, but restricted in some regions. OKX: Strong overall, rich derivatives, low fees, great for futures trading. Coinbase: Most compliant in US, highest security, but higher fees, fewer coins, suitable for compliance-focused users. Choose based on your needs and location.
Q3: How to judge if an exchange is safe?▼
Key indicators: 1) Holds regulatory licenses (US MSB, HK VASP); 2) Has Proof of Reserves; 3) No major security incidents; 4) Supports cold wallet storage; 5) Has insurance fund; 6) Transparent financials. Avoid: unlicensed, newly established, opaque team, promises high returns.
Q4: How are exchange fees calculated?▼
CEX fees typically include: spot trading fees (0.1%-0.2%), futures fees (0.02%-0.05%), withdrawal fees (fixed or by coin). Higher VIP levels get lower fees. DEX fees include: trading fees (0.25%-0.3% to LPs), gas fees (can be high during congestion). Compare total trading costs, not just rates.
Q5: Is it safe to keep funds on exchanges?▼
