This is a scam site.
No explanation for cancelling my winning bets yet.

They say they will give me a report, but it is all lies, what kind of report needs 6 months?!?

They know I did not use any bug, they just hope to find something because I won some bitcoin and they don't want to pay out.
All there is left is people to stay away from them because if you lose you lose, if you win they void.
