Solved, received the money all ok, 31.96860000 BTC.
But still sad about situation and idk should i play there anymore, hope they will solve all problems with payments.
That's just proves that rollbit is a legit casino. I think that the provider did verify it and then rollbit have payed your withdrawal request. Just keep in mind that the amount you did withdraw is not a small amount so it's natural that it will take some time before it is processed. Even if the withdrawal takes longer as you have waited but at least they paid you. How I see this is that they value their reputation that much.
I doubt that most of this thread users will have problems with this casino because no one is withdrawing that much. If Rollbit wants to prove its credibility and transparence to high rollers, they should pay you a little bit more for this inconvenience.
It's not a small amount and they ask the provider to verify the bet.
