I am quite sure, other casinos will do the same as what Rollbit did because of your account activity. Created an account-deposited 330$-bet $10 only-tried to withdraw remaining balance. If you are an experienced gambler, I do not think you will do it although you cant bet on what you want because of a reason. At least, you should have wagered more in other events or maybe in other casino games so your account activity is not considered as suspicious.

Lesson learned for you, do not do the same thing again in other casinos. Every casino has their own terms, if you are proven to break one of their terms, you should accept the consequences. No other thing I can suggest except: try to contact rollbit's bitcointalk forum by private message and hope there will be a way to solve it.
