What is a Centralized Exchange (CEX)?
Centralized Exchanges (CEXs) are a type of cryptocurrency exchange that’s operated and controlled by a company. They are online platforms used to buy and sell crypto. Essentially, they’re like a marketplace. They’re useful when a lot of people are simultaneously trying to buy and sell the same type of assets. They also have similar business models to traditional exchanges like stock exchanges.
Centralization refers to the use of a middle man or third party to handle assets. This is similar to a bank, where customers trust the bank to hold their money. This adds an additional layer of security and monitoring. The same principle applies to centralized exchanges.
CEXs facilitate trades between users by maintaining an order book, which are buy and sell orders posted by individual traders. Orders are requests to buy or sell a certain amount of crypto at a certain price. CEXs can be used to conduct trades from fiat to crypto (or vice versa) or to convert exchanges between two different cryptocurrencies.
The reliance of CEXs on a central entity does have some disadvantages.
Overall, CEXs are the most common and easiest way for beginner investors to enter the crypto space. The speed and cost-efficiency of processing trades make them especially convenient for buying and selling crypto.
