The majority, if not all, of crypto gambling sites will not allow you to use a different method to withdraw from the one that you used to deposit. This is due to anti-money laundering and anti-fraud laws. No one should be able to use online gambling sites in order to “clean” money obtained illegally, nor use credit card numbers that have been hacked or stolen from unsuspected individuals. Of course, there are some exceptions, but certainly you will need to go through a process where you should prove that you are behind every deposit that you have made so far.
