I don't want to accuse anyone, but this seems like a strange gambling pattern. And all small bets and the last 600. I think 1xbit also thinks this is a separate betting pattern. Even at the highest level, strange things happen in the world. I don't know why 1xbit canceled the bets, but it could be that the terms and conditions have been violated. I think 1xbit reserves the right not to announce that either, because cheaters then know how to use a new exploit on that.
