Frequently Asked Questions
Which is safer, DEX or CEX?
Neither is universally safer. DEX eliminates counterparty risk (exchange collapse) but introduces smart contract risk (bugs). CEX has institutional security but can be hacked or go bankrupt (e.g., FTX). Self-custody after CEX purchase is the safest approach.
Can beginners use DEX?
Yes, but with caution. DEXs like Uniswap have simple interfaces, but users must understand gas fees, slippage, and token approval risks. Start with small amounts and learn wallet security first.
Why do traders prefer CEX?
CEXs offer faster execution, better liquidity, advanced order types, and fiat onboarding — essential for active traders. They also provide customer support when something goes wrong.
