CEX and DEX both have a good reputation with their blockchain systems. For example, Ripple which has a CEX blockchain system, but also gains the trust of the public to invest even though it has had problems recently. Likewise with the DEX concept. Many projects are currently making DEX blockchain systems, but they add the number of coins in a different form, namely by developing coins in different blockchain systems, so the number of coins also increases even though on the initial blockchain they are fixed.
