You can expect your balance to be refunded to your account if you are talking about a reputed site but already their reputation is ruined on Bitcointalk but still they are growing bigger and bigger with lot of promotion from outside of bitcointalk.
This is alarming to be honest, the people advertising outside of the forum doesn't know that this site is one big scam. I thought that they have already deleted their thread on the gambling but now I am not surprised considering they still have the audacity to promote their website. Hopefully, someone outside the forum is going to discover their schemes because there is a possibility that more people are going to be scammed post forum incidents.
