Just to stray away from all the others here and back on point. 1xbit and its mother company 1xbet has been proven to be both scams. They have unjustly confiscated account balances and forfeited winnings as well in the past, this can be easily be researched as there have been a lot of public outcries here on the forum and all over the internet.
I was actually not aware of this.. I almost registered an account a while back but never did as I found some other site or something.. Lucky me I guess.. Also made a few searches just now and yeah, it does not look good for either of those comapnies. Hopefully they won't get any more customers but sadly some people just sign up blindly without checking if everything is legit.
