#CEXvsDEX101 # CEX vs DEX 101: Understanding Centralized and Decentralized Exchanges

Cryptocurrency trading has evolved significantly since Bitcoin's inception. One of the fundamental choices every crypto user must make is where to trade — on a Centralized Exchange (CEX) or a Decentralized Exchange (DEX). Each has its strengths and weaknesses, and understanding the difference is crucial for making informed decisions.

*What is a Centralized Exchange (CEX)?*

A CEX is a platform managed by a company or organization that facilitates the buying and selling of cryptocurrencies. Key features include:

- *Operated by a central authority*: Examples include Binance, Coinbase, and Kraken.

- *User-friendly interface*: Often includes mobile apps, advanced charts, and fiat on-ramps.

- *High liquidity*: Easier to execute trades quickly at stable prices.

- *Customer support*: Available for users.

*What is a Decentralized Exchange (DEX)?*

A DEX operates without a central authority, relying on smart contracts and blockchain protocols to enable peer-to-peer trading. Key features include:

- *Non-custodial*: You control your funds and private keys.

- *No KYC/AML*: More privacy and anonymity.

- *Open-source and censorship-resistant*: Examples include Uniswap, PancakeSwap, and dYdX.
