First of all, I am not sure if the Op is asking for the Dex or Cex's but as most of the marketing is done by the centralized exchange in that context I think as always what I stated whether you like or not the centralized exchanges made a lot of contribution in the global crypto recognization and adoption as well with their marketing strategy and other services a lot of people started their payment mode and service exchange with crypto market. In the future as well they are gonna make a big sound in global adoption.

But as most people are concerned about their privacy and self custody so they use the centralized exchange but most of the new users are still dependent on the centralized exchanges. I also prefer using the DEX but I use to appreciate the contribution of the centralized exchanges in this market and global adoption.
