good if you managed to make some changes in that thread alone
Unfortunately the license of 1xbit is issued by Caracao so it's not in my expertise.
The only input I can place in here is that, 1xbit do have a registered address in Caracao.
I have heard of stories players won their case in the court in Caracao.
So if they have a great balance on the account then they can give it a shot.
However, it's not my expertise so I'd advise them to contact someone who is familiar with the process in Caracao.
Also, personally I'm not familiar with 1xbit, but working in this business I do aware some people are exploiting casinos for their own agenda.
This could includes but not limited to money laundering and other offense, and they're usually done through multi accounting or even run by a syndicate.
And casinos are bonded by law not to share the information to the public, because the same person could learn from there and use another method next time.
So I'm not surprise to see people have negative feedbacks toward casinos from time to time.
But some people are not as innocent as they claim to be, so it will be hard to ask them to fight for their case through the court because they don't want to expose themselves.
