TLDR
You can trade cryptocurrencies on both centralized exchanges (CEX) and decentralized exchanges (DEX). This guide explores their differences, pros and cons, and key factors to consider when choosing between them.
- CEXes (e.g., Binance, Coinbase) are run by a single entity, offering user-friendly interfaces, high liquidity, and regulatory compliance but require custody of user funds.
- DEXes (e.g., Uniswap, PancakeSwap) operate without intermediaries, prioritizing privacy, security, and control over assets but may lack liquidity and ease of use.
Understanding these differences helps you make informed decisions based on your trading needs.
Introduction
Cryptocurrency exchanges are platforms for buying, selling, and trading digital assets. They fall into two categories:
- Centralized Exchanges (CEX): Managed by companies, these platforms act as intermediaries, offering fiat support, high liquidity, and regulatory oversight.
- Decentralized Exchanges (DEX): Peer-to-peer platforms powered by blockchain, enabling non-custodial trading with greater privacy but often steeper learning curves.
This article breaks down their features, security models, fees, and more to help you choose the right exchange.
Centralized Exchanges (CEX)

CEXes like Coinbase, Binance, and Kraken dominate the crypto trading space. They provide:

FAQ
1. Which is safer: CEX or DEX?
CEXes offer insurance and support but are prone to hacks. DEXes eliminate custodial risk but require self-security measures.

3. Why choose a CEX?
Opt for CEXes if you prioritize ease of use, liquidity, and fiat support.
