hahah that is a funny question, obviously it goes to the pocket of the casino?? But! Due to forum pressure, protecting public image, etc etc
a lot of casinos would eventually let the user get that money regardless. But, if the wrong doing of the user is severe, the casino is keeping that money,
maybe in good gesture they might reimburse the initial deposit, but not guaranteed!
The money will be in the casino especially if that is a scam casino. They will not let their members get their money and will not give an answer to their questions. Maybe the casino hold the fund because casino found something suspicious with their members. So they need to check everything before they process the next thing. But if that a good casino, they will let their members get their money after the checking finish.
That is why you need to research before you choose the casino. That will help you to stay away from a scam casino.
