But I spoke with the support team and they were very helpful, we finally found the source of the problem.
Until they update the site, I would advise you to only deposit from a personal wallet and not from an exchange as it might cause problems.
I played a bit on the site and up until now, it is the best bitcoin casino I have seen!
They also said that they may put a warning beside the deposit address advising players not to deposit directly from an exchange until they update the site.
So it's all resolved now thanks to their support team.
Thanks for the compliment! Glad you got this resolved. Happy gaming!
