1xbit has many such accusations in the scam accusations subforum of Bitcointalk and even others in other forums. It is obviously a scam casino or a very unprofessional casino run by idiots.

This is why I always tell people, especially newcomers to the world of gambling, in this case crypto gambling, that the minimum amount of research you should do before putting funds in a casino is to google two words. "[casino name]" and "scam". If the first page shows people complaining about being scammed by said casino, you can do more research if this is happening to more than a few people.

But it seems people have too much money to care about being scammed nowadays. Whats the point of doing your own research if one is too lazy to google?
