Look at this post from the 1xbit announcement thread so you can see how its link to 1xbit.
Look at this

If you are convinced that they are link, I would suggest that you get yourself ready to accept the reality that you might not be able to get your money because they probably have the same reputation since they are link with each other. Sorry for your loss mate but I hope your problem will resolve.
I’m doubtful if you notice that the casino involved here is 22bet.com and not B2B like what stated on the post that you share. Is there any proven connection between this 2 casino or you just overlooked it when you share the post made on 1xbit thread?
I'm just trying to connect the dots here as I've read this post above and I think there was a connection with B2B and 1xbit.
By the way, I don’t know how much this is relevant to this thread but I read somewhere that both 1xbit.com and 22bet.com are using the same type of software - which is “BetB2B” - you really need to be careful when dealing with site that has anything to do with 1xbit.com, for what we know they could have other sites that are theirs but not yet linked and exposed to the public.
They are really everywhere, making similar casinos that are coming from one software provider or operator, we dont know anymore but we should consider that when there is a linkage, we have to doubt its reputation already, must possible not to gamble anymore and this community should be a tool for the users to be aware of their possible connection.
