Knowing the rules is an obligation, it's the same as; eating, drinking, and breathing.
Indeed. We don't want to be put in a situation because of our negligence to know their rules right? Thus it's a must for us to do our part before playing to avoid having inconvenience because if you already face a problem on their platform (and you're at fault), it's not an excuse that you don't know the rules.
Anyway, nowadays there are many casinos existing already, that means plenty of choices for gamblers to look for a casino that they prefer. As we know, some gamblers are still not fine to comply if there's a kyc requirement and this is a common issue.
Issues like KYC is never that big because in the long run, all centralized casinos will obviously require KYC to be compulsory, so there’s no escaping from it really. But when it comes to withdrawals, I think that will be a big issue especially if the company itself is neglecting your concern, and it takes long hours of waiting before your problem gets attended.
