CEX
Centralized Exchange. A cryptocurrency trading platform operated by a centralized company that acts as an intermediary between buyers and sellers.
Why It Matters
A CEX (Centralized Exchange) is a platform where users can buy, sell, and trade cryptocurrencies, often with fiat currency. They are crucial for beginners looking to enter the crypto market easily and securely.
Example
For example, platforms like Binance or Coinbase act as CEXs where you can trade Bitcoin for Ethereum. They manage the order book and facilitate transactions between users.
Beginner Context
As a newcomer, knowing about CEXs is important because they are often the first step for buying cryptocurrencies. They provide user-friendly interfaces and essential services for trading.
