I think you're confusing 1xBet (which appears to be legitimate) with 1xBit. They are not the same entity, and although there's speculation that they're affiliated, I doubt that too. I suspect that the scammers behind 1xBit chose the name to take advantage of the recognition and fame of 1xBet.

If a business is legit, why are they acting so guilty? Why not at least just say, "we don't know them"?
