Introduction
Cryptocurrency exchanges are the backbone of the crypto ecosystem, allowing users to buy, sell, and trade digital assets. However, not all exchanges are the same. There are two main types:
👉 Centralized Exchanges (CEX)
👉 Decentralized Exchanges (DEX)
Understanding the difference between them is essential for anyone entering the world of crypto trading.
Cryptocurrency exchanges are a key part of the ecosystem. If you're new, first understand what is a crypto exchange and how it works.
Centralized exchanges (CEX) are platforms managed by companies that act as intermediaries for buying and selling cryptocurrencies, offering high liquidity and ease of use. Decentralized exchanges (DEX) operate without intermediaries, allowing users to trade directly from their wallets using smart contracts. While CEXs provide convenience and speed, DEXs offer better privacy and control over funds.
