What does a mean CEX?

Excuse me, but could you please clarify what you mean by "a mean CEX"? It seems there might be a bit of confusion in the terminology. Are you referring to a "centralized exchange" (CEX) in the context of cryptocurrency trading? If so, a centralized exchange is a platform that facilitates the buying and selling of cryptocurrencies between users. It serves as an intermediary between buyers and sellers, ensuring that transactions are secure and efficient. The platform maintains custody of users' funds and often provides additional services such as trading pairs, order books, and market data. Is this what you were asking about?
