Crypto Exchanges: Centralized vs Decentralized

Custodial: The exchange holds users’ funds and private keys, similar to a bank holding your money.

User Experience: CEXs offer user-friendly interfaces, fast trade execution, and customer support, making them accessible for beginners.

Liquidity: They typically have high trading volumes and deep liquidity, allowing for quick and large trades with minimal price slippage.

Fiat Integration: Users can deposit and withdraw fiat currencies (like USD, INR) and trade them against cryptocurrencies8.

KYC/AML Compliance: Most require users to complete Know Your Customer (KYC) and Anti-Money Laundering (AML) procedures, submitting personal identification for regulatory compliance.

Order Book System: Trades are matched via an internal order book managed by the exchange.

Easy to use, with support and educational resources.

High liquidity and fast transaction speeds.

Wide range of trading pairs and features, including derivatives and margin trading.

Regulatory oversight may offer some protection to users.

Users do not control their private keys; “not your keys, not your coins”.

Vulnerable to hacks and security breaches since funds are pooled in hot wallets.

Subject to regulatory restrictions and potential government intervention.

Can freeze accounts or restrict withdrawals at their discretion.

Non-Custodial: Users retain control of their funds and private keys at all times.

Peer-to-Peer Trading: Trades are executed directly between users via smart contracts, without a central authority.

No KYC: Most DEXs do not require identity verification, allowing for anonymous trading.

Crypto-to-Crypto Only: Typically, DEXs do not support fiat currency deposits or withdrawals—only crypto pairs8.

Automated Market Makers (AMMs): Many DEXs use AMMs and liquidity pools instead of traditional order books to facilitate trades7.

Users maintain full control over their assets and private keys.

Lower risk of large-scale hacks, as there is no central fund pool.

Greater privacy and anonymity; often no KYC required.

Lower transaction fees in many cases.

Censorship resistance—no central authority can freeze funds or block trades.

Lower liquidity compared to major CEXs, which can lead to price slippage, especially for large trades or less popular tokens.

More complex user interfaces and processes, requiring greater technical knowledge.

No customer support—users are responsible for their own funds and troubleshooting.

Vulnerable to smart contract bugs and exploits.

Limited trading options (usually only crypto-to-crypto).
