#CEXvsDEX101 Despite the rapid evolution of Decentralised Finance (DeFi), CEXs remain enormously popular due to the high level of liquidity and security. CEXs use the order book system to match bid and ask price, which means the more orders there are, the more liquid the market is. CEXs also provide fiat- crypto trading pairs and act as the guarantee for the completion of transactions. They are especially beginner-friendly – most individual investors made their first crypto transactions “on-ramp” or, in simpler terms, with their credit cards. Bitget is one excellent example of major centralised trading platforms, with 2 million users (8,000 of which are active daily) and ranking 3rd worldwide in terms of liquidity.
