Sorry to hear about that, 1xbit is the worst gambling site that's still operational to ever grace crypto space. Those low lives are a bunch of shameless scammers.

You should have known this before registering, and depositing any money into their platform. Once you make some decent winning, they block your account and say you violated some rules they will never mention to you.
They always hide behind the invincible rules you violated and the best offer they can make is to just return you deposit.

So basically, they will be very glad if you keep losing to them but once you make winnings, you get locked out...
