What Is a Centralised Exchange (CEX)?

A centralised exchange (CEX) is a platform that allows users to buy and sell cryptocurrencies with traditional fiat currencies or other cryptocurrencies. CEXs act as intermediaries between buyers and sellers, holding users’ funds and facilitating transactions.

Centralised exchanges, like the Crypto.com Exchange, are popular because they offer a wide range of products and features. These exchanges also typically have high liquidity, which means users can buy and sell cryptocurrencies quickly and easily. Additionally, many centralised exchanges allow users to buy cryptocurrencies using fiat currencies, while also allowing fiat offramps; these features are usually not offered by decentralised exchanges (DEXs) in comparison.

Benefits of CEXs

Ease of Use

Centralised exchanges tend to be easier to use than decentralised exchanges because they offer a user-friendly interface alongside customer support, which decentralised exchanges don’t tend to offer.

Variety of Assets

Centralised exchanges tend to offer a wider variety of assets than decentralised exchanges, which includes more trading pairs. This can be beneficial for traders, as it allows them to diversify their portfolio and potentially find new opportunities. Centralised exchanges are also quicker to list new coins and tokens that are not available yet on decentralised exchanges.


Centralised exchanges generally have higher liquidity than decentralised exchanges. This is especially important for traders who need to make large trades or want to take advantage of arbitrage opportunities. Higher liquidity means that the spread is minimal between trading pairs, which is what users look for when choosing a centralised exchange, as it ensures that trades happen quickly at a fair market price.

Customer Service

Centralised exchanges tend to offer better customer support than decentralised exchanges, which tend to not offer individualised customer support. CEXs help to answer questions or solve problems through chat or email, in addition to informational pages and FAQs.

Overall, choosing between a centralised exchange and a decentralised exchange depends on individual needs and priorities. Some prefer a non-custodial decentralised exchange, while others appreciate the ease of use and liquidity of a centralised exchange.

Challenges of CEXs

Advanced Security Demands

Many centralised exchanges hold users’ funds in a single wallet, making them targets for hackers. If an exchange is hacked, the attackers may be able to steal users’ funds, which could result in significant financial losses. When choosing an exchange, DYOR on how and where the exchange stores funds.

Crypto.com keeps users’ funds in various locations, including cold storage offline accounts. Learn more about Crypto.com’s industry-leading security features here.


Another challenge for CEXs is the exchange experiencing the equivalent of a bank run. If an exchange is unable to pay its debts or otherwise goes bankrupt, users may lose access to their funds. Check if the exchange discloses a public Proof of Reserves (PoR) that proves they are still holding the funds.

Crypto.com has recently published its PoR, which allows users to verify that all customer crypto deposits are held by Crypto.com on a 1:1 ratio. 


Depending on crypto legislation, exchanges might not be able to operate or offer the full width of their services in all jurisdictions. Check if the exchange is able to offer the desired services for pertinent countries.
