How can be so sure with this line? because most trader do use up centralized exchange doesnt mean they dont know how to use DEX? I dont think so, i do rather believe that most people do know how to use that if not then using dex arent really to technical even having an average knowledge on how crypto works will definitely get the idea on how to use up. I know how it feels on going contrary on how should crypto be but dealing with fiat transactions you wont really have any choice.
