Hi, Posi,
1st of all 1xBit paid them regularly, they paid them 21 weeks previously, and then the new 30 weeks are ongoing. they won't have to face any problems with their payment at all. So I think 1xBit is legit.
2nd, if a casino is able to spend more than 3000+ USD weekly on their participant faithfully then also they have the ability to take care of their respected user. No user lost their funds on 1xBit, which are past.
