Unfortunately, but in a situation where the player claims one thing and the casino the other, and neither side can present evidence, it is difficult to take one side.
I am guided by the fact that, unlike in the past, now 1xBit support responds to all issues on a regular basis and I believe that, like Betcoin.ag, it will rebuild its reputation.
I know that most users are driven by the past now, but I believe that it will change over time.
since you mentioned that evidence thing , is there a chance that your Bosses will provide this Evidence you are saying ? or will keep hiding in their rules and regulation thing ? if the players/victims can provide not just one but many proofs, then why your BELOVED COMPANY does not have even one?
I think that if someone uses multi accounts, such data cannot be disclosed to the public by casino. I also doubt that the player who used multi accounts will admit it. This is a situation that does not allow to stand on either side, because neither side will present evidence.
