Many messenger applications have been created but for Blockchain-based ones, it might just be in Mixin,hope that in the future it can still exist..
While this might be true.... Have you tested out Mixin and compared it to ANY of the competition?
It's like comparing a Lambo to a '80s ford pickup. Mixin looks great, and connects to a variety of blockchains.
My only advice would be to get XIN on more exchanges. The current options are garbage
