I do not know about this service whatsoever, but why would anyone give their money to another person or entity to gamble if you can do the gambling yourself instead? 

Is this some kind of a easy-money scheme I had not heard of, because sounds rather like a scam. Initially thought it was a bot which allowed people to exchange casino money for other coins outside the casino (I am not sure whether that goes against the ToS or not, by the way)
