There are still no any news in english or at all in project medium page and also twitter account is suspended now, very strange
You're right about their medium page like not used properly, there are only 2 old news there, nothing new. However, their twitter account is fine I think, because I just tried to go to the
https://twitter.com/QUAI_GLOBAL profile, it works as usual, not has been suspended. Also, projects like this will not let their twitter account get suspended or take too long, they will definitely take care of it.
