FAQs About Centralized Exchanges

1. Is a CEX safer than a DEX?

CEXs offer robust security (e.g., insurance funds), but users must trust the platform. DEXs eliminate third-party risk but require self-custody.

Yes! Most CEXs support USD, EUR, and other fiat currencies via bank transfers or cards.

3. Why does liquidity matter?

Higher liquidity ensures tighter spreads and faster order execution.


Conclusion

CEXs dominate crypto trading due to their convenience, liquidity, and security. While DEXs grow in popularity, centralized platforms remain the go-to for beginners and high-volume traders.
