I have the same issue! 1xbit is very dodgy and does not pay the winnings! After I won my account was blocked and I received email saying I made fraud.
I will be posting everyday about status of my funds until they are returned. If not I will be posting user reviews about 1xbit and their parent company 1xbet from other websites, to keep customers here informed (with sources).
Also to the guys who are doing the signature campaign - Do your research! This is shady and dodgy website and YOU advertise it. You are advertising scammers! Do not put under threat your reputation by doing so!
If you all guys very sure that you have valid proofs to support your accusation then just simply create scam accusation thread. It will help other people to stay away, but if you are only saying without proofs then it wont affect anything.
As far as I see from various internet sources it is full of scam accusations to 1xbit and parent 1xbet. That is why I will post them here daily.
Regarding proof - 1xbit did neither ask me for any verification procedures, nor informed me about the clear reason of closure (Just saying violation of Terms and Conditions). I am more than happy to provide them with documents and go through any verification procedure they have.
Accusing someone without evidence also can have consequences. I understand that you are upset, but just spamming this thread will not help you. What is your target? If you want clarify this situation, ask about that 1xbit support - that is their job. How someone can help you here if you don't give us proofs?
Write ticket to support and wait for answer. If you have proofs - show us here or open scam accusation thread.
I also wrote to support and It take them many weeks to answer. I still cannot withdraw funds that I uploaded from my wallet.
Here is some evidence, as you want, for my case:

Explain why this can take, so much time!
