What options do you have when they won't?
Thanks in advance.
The most common one is the KYC, looks like casinos love that method to hold the users profit, and casinos have some advance kick levels, the hard part of the KYC is to prove your source of income, and that's the step where a lot of users lose their money.
And another common one is the multiple accounts, if you have more than one account with the same IP, then the casino will block the withdrawals, and isn't fair at all because sometimes multiple users play in the casino from the same location, and that doesn't mean they are the same user.
