The fund will still in our account and it is ready for withdraw after we do KYC. Before that, we can still use that money to gamble but we need to do KYC to withdraw the win money especially if the money become bigger.
Asking for a help to support will be better to solve our problem so we don't make a mistake. If they say that we can skip the next verification, we can pass that and try to withdraw the money. Unless we can not do that, we can back to the support and ask for what we can do to withdraw the money.
If you can not withdraw your money without KYC, there is risk that you will lose your fund. Because KYC can be approved or refused and your fund will be locked there if KYC failed.
Take care of your fund safety and ability to withdraw it is more important than using it to bet, win big and at the end you won't be able to withdraw it. It will be like amplification of your pain when not only initial capital is locked but your big win is confiscated too.
So before you deposit your money, if a casino requires KYC, let's do KYC successfully before making your deposit and start to bet.
