This comprehensive guide delves deep into the features, benefits, and drawbacks of both CEXs and DEXs, providing you with the knowledge to choose the platform that best suits your individual needs and risk tolerance.

Frequently Asked Questions (FAQ)

1. What is the main difference between a CEX and a DEX?

2. Is a CEX or a DEX safer?

   Typically, no. DEXs are designed to be permissionless and do not require Know Your Customer (KYC) verification.
