TL;DR - Quick Comparison

| Feature | Centralized Exchange (CEX) | Decentralized Exchange (DEX) | |---------|---------------------------|------------------------------| | Custody | Exchange holds your funds | You hold your funds | | KYC Required | Yes (usually) | No | | Trading Experience | Fast, familiar (order books) | On-chain, requires wallet | | Liquidity | Very high | Lower (but improving) | | Fees | 0.1-0.5% trading fee | 0.05-0.3% + gas fees | | Security Model | Trust the exchange | Trust smart contracts | | Asset Variety | Major cryptocurrencies | Long-tail tokens | | Fiat On/Off Ramp | Yes (easy) | Limited (requires bridges) | | Regulation | Heavily regulated | Varies by jurisdiction | | Privacy | Low (KYC required) | High (pseudonymous) | | Hacking Risk | Exchange can be hacked | Personal wallet responsibility | | Best For | Beginners, fiat trades, high volume | DeFi users, privacy-focused, self-custody |

What is a Centralized Exchange (CEX)?

Definition

A centralized exchange is a platform operated by a company that facilitates cryptocurrency trading. The exchange acts as an intermediary between buyers and sellers, holding customer funds in custody.

How CEX Works

1. Registration: Create account with email and password
2. KYC Verification: Submit identity documents
3. Deposit: Send crypto or fiat to exchange wallet
4. Trading: Place orders on order books
5. Withdrawal: Request withdrawal to external wallet

Major Centralized Exchanges

Top CEX by Volume (2025):

1. Binance - $50B daily volume
2. Coinbase - $15B daily volume
3. Kraken - $8B daily volume
4. OKX - $12B daily volume
5. Bybit - $10B daily volume
6. KuCoin - $5B daily volume
7. Bitfinex - $3B daily volume
8. Gemini - $2B daily volume

CEX Architecture

Backend Components:

• Order matching engine
• Custody wallets (hot + cold storage)

What is a Decentralized Exchange (DEX)?

Definition

A decentralized exchange is a peer-to-peer marketplace where trades execute via smart contracts without intermediaries. Users retain custody of their funds at all times.

How DEX Works

1. Connect Wallet: Use MetaMask or similar
2. No Registration: Anonymous, no KYC
3. Trading: Approve tokens, execute swaps on-chain
4. All On-Chain: Every transaction is blockchain transaction
5. Self-Custody: You control private keys

Top DEX by Volume (2025):

1. Uniswap - $1.8B daily volume
2. Curve - $800M daily volume
3. PancakeSwap - $650M daily volume
4. dYdX - $2.5B daily volume (derivatives)
5. SushiSwap - $280M daily volume
6. Balancer - $300M daily volume
7. GMX - $450M daily volume
8. Trader Joe - $180M daily volume

DEX Models

Automated Market Maker (AMM):

Comprehensive Feature Comparison

1. Custody & Control

Centralized Exchanges: Custodial Model

How it works:

• Exchange controls private keys
• Your coins stored in exchange wallets
• You have account balance (IOU)
• Trust required

Analogy: Like a bank - you deposit money, they hold it, you can withdraw.

Advantages: ✅ No need to manage private keys ✅ Can recover account with password reset ✅ Exchange handles security ✅ Simple user experience ✅ Customer support available

Disadvantages: ❌ "Not your keys, not your coins" ❌ Exchange can freeze your account ❌ Exchange bankruptcy risk (Mt. Gox, FTX) ❌ Withdrawal limits may apply ❌ Dependence on third party

Historic Failures:

• Mt. Gox (2014): 850K BTC lost
• QuadrigaCX (2019): $190M inaccessible
• FTX (2022): $8B+ customer funds lost
• Celsius (2022): Bankruptcy, funds locked

Decentralized Exchanges: Self-Custody

How it works:

• You control private keys via wallet
• Funds never leave your wallet until trade
• Smart contract executes swap atomically
• No intermediary

Analogy: Like peer-to-peer cash exchange - direct ownership.

Advantages: ✅ Full control of funds ✅ No account freezing ✅ No withdrawal limits ✅ No exchange bankruptcy risk ✅ Permissionless access

Disadvantages: ❌ You're responsible for security ❌ Lost keys = lost funds forever ❌ No customer support for wallet issues ❌ Must understand wallets and gas ❌ Mistakes are irreversible

Key Principle: With great power comes great responsibility.

Recommendation by User Type

Choose CEX if:

• New to crypto
• Don't want key management responsibility

• Selfie verification
• Source of funds (for large amounts)

Privacy Implications:

• Exchange knows your identity
• Links identity to all trades
• Must report to tax authorities
• Data breach risk
• Transaction monitoring

Verification Levels:

| Level | Requirements | Limits | |-------|-------------|--------| | Level 1 | Email only | $1K-5K withdrawal/day | | Level 2 | Basic KYC | $50K-100K/day | | Level 3 | Enhanced KYC | Unlimited |

Advantages: ✅ Regulatory compliance ✅ Fraud prevention ✅ Can link to bank accounts ✅ Dispute resolution

Disadvantages: ❌ No privacy ❌ Data breach exposure ❌ Government surveillance ❌ May be censored

Frequently Asked Questions

Q: Is it safe to keep crypto on an exchange? For small amounts and short-term, yes. For large amounts or long-term, move to personal wallet.

Q: Can I get hacked using a DEX? DEX itself is safer, but your wallet can be compromised through phishing or malware.

Q: Which has lower fees? Depends on trade size and chain. Generally CEX for large trades, DEX on cheap chains (BSC) for small trades.

Q: Do I need KYC for DEX? No, DEXs don't require KYC. But you may need CEX (with KYC) to buy crypto initially.

Q: What if I lose my password on a CEX? You can reset it. But if you lose DEX wallet keys, funds are gone forever.

Q: Are DEXs legal? Currently yes, but regulations are evolving. Some jurisdictions may restrict access.

Q: Can CEX freeze my account? Yes, due to suspicious activity, regulations, or ToS violations.
