Actually, as far as I know, 1xBet is a FIAT bookmaker+casino and this topic should not be on Bitcointalk at all. Unless we connect it with 1xBit, their daughter company that operates on the cryptocurrency market.
Either way, we should soon find out if this story is true. Because if it is made up, it means that 1xBit/1xBet is coming back with a promotion on Bitcointalk and we will soon see another campaign. If it is not made up and the OP got his money back, there will be silence and, strangely enough, trust in 1xBet will increase.
1xBet is the parent company of 1xBit.
I actually put that on Wikipedia some time ago but sneaky paid actors keep deleting it, so you're not going to find that info there.
Anyway... there is a reason why 1xbet is banned in virtually so many places and the CEO is a wanted man. Stay away from all of the 1x casinos unless you want to lose money in a guaranteed way.
