Frequently Asked Questions About Crypto Exchanges
What is the main difference between centralized and decentralized exchanges?
The primary difference is that centralized exchanges (CEX) hold custody of your crypto assets and require user identification, while decentralized exchanges (DEX) allow users to maintain control of their funds through self-custody wallets and typically don't require formal identity verification.
Which type of exchange is safer for crypto trading?
Both types have different security models. Centralized exchanges may be vulnerable to hacks but often have insurance funds and better recovery options. Decentralized exchanges eliminate custodial risks but rely on smart contract security and require users to properly secure their own wallets.
Are decentralized exchanges better for privacy?
Yes, decentralized exchanges typically offer greater privacy as they don't require KYC verification and operate on blockchain networks where transactions are pseudonymous, although still visible on the public ledger.
Which exchanges have the lowest fees?
Centralized exchanges generally have lower direct trading fees than decentralized exchanges. However, DEX fees can vary significantly depending on network congestion and gas prices, with exchanges on Layer 2 solutions or alternative blockchains offering lower fees than Ethereum-based DEXs.
