Overview of Centralized Cryptocurrency Exchanges (CEX)
Centralized cryptocurrency exchanges (CEXs) are online platforms operated by companies or institutions where users buy and sell cryptocurrencies.Unlike decentralized exchanges (DEXs), CEXs require users to deposit funds into accounts controlled by the exchange, with the platform responsible for matching buy and sell orders and safeguarding user assets. This model gives CEXs significant advantages in terms of trading speed, liquidity, and fiat currency deposits and withdrawals, but it also means that users do not directly hold the private keys to their crypto assets.
Market Dominance and Regulatory Trends
As of 2026, centralized exchanges remain an indispensable part of the cryptocurrency market, accounting for over 80% of cryptocurrency trading volume and serving as a core pillar of price discovery and market liquidity.
Regulatory oversight of cryptocurrency exchanges is becoming increasingly stringent across major global jurisdictions. For example, regions such as the United States, Japan, and European Union member states have established licensing systems and require exchanges to comply with anti-money laundering (AML) and know-your-customer (KYC) obligations to ensure transaction compliance and transparency.
