StellarX is great. The only problem - there are not enough good projects built on Stellar except Gratz and Mobius It needs more high-quality interesting projects.
I cant really deny that Stellar platform is a good one but same as you said only a few projects built into this platform are better. Centralized exchange are quite
famous than on Dex ones but knowing Stellar they are more into dex but i wont really surprised if they would comply with such requirements about being centralized.
