From what I see 0xbet is a brand owned by Boomerang which is a Russian casino and sportsbook. There are several other brands in Boomerang's portfolio. Am I right? Having multiple crypto casino brands seems suspicious to me, but I might be wrong.
I've visited 0xbet and most of the games can't load. There's a sign that says "something went wrong, please try again later".
Anyway, the casino looks pretty much OK and the owner has a Curacao gambling license.
Good luck with this project, OP.
