1xbit is as shady as it gets, full stop - the "promises" here on bitcointalk with pretty much no change of attitude are making it worse.
Too bad that money rules, you can (of course) still find their ads all over the internet (and not just online) - that is even though it`s very well known by now that they (1xbet/betb2b group) have been shady for years.
TBH, I had some mini hope they would at least try to make up here on bitcointalk when their reps were talking to me but turns out, thin air... So yeah, stay away, the fact they are present everywhere doesn`t mean they wouldn´t scam.
