#中心化与去中心化交易所 CEX (Centralized Exchange): Handing over money to the "bank"🏦

✅ Custodial Model: Your coins are like deposits in Alipay, the exchange helps you keep them safe (big platforms like Binance/Coinbase have fund pools in the hundreds of billions)

✅ Order Book Trading: Buyers and sellers quote prices, the platform matches them in seconds, and contracts can be closed in minutes (if you're slow, you'll really regret it!)

✅ Regulatory Compliance: Real-name authentication + KYC, the U.S. SEC is watching (Coinbase has been sued before, isn't that exciting?)

DEX (Decentralized Exchange): Be your own "manager"🗝️

✅ Non-Custodial Model: The private key is the safe key, even if hackers come, it won't matter (Uniswap/SushiSwap can be used directly with wallet connection)
