What Is a CEX? The Complete Centralized Exchange Guide

Introduction: Understanding CEXs in the Crypto Ecosystem

What is a CEX? A CEX, or Centralized Exchange, is a cryptocurrency trading platform operated by a central authority that enables users to buy, sell, and swap digital assets. These platforms act as intermediaries between buyers and sellers, much like traditional stock exchanges.
