if you don't want to withdraw money without KYC you should play decentralized casino because it's safe and without KYC but if you play centralized casino you should follow the rules of the game as they also have rules you have to follow, I'm also not interested in giving KYC then from that I always avoid it let alone withdraw big money of course I will be asked to submit KYC
Some people found themselves in this unwanted KYC position because the gambling website failed to state the fact about KYC verification where every new user can easily read and know what they are going into, I believe they are doing this intentionally, they knew some people will stay away from their website because of KYC verification, but after they win some money they have to abide to get their money withdrawn, users will have no choice but to pass the KYC to get their money out.
There are some things which the casino can't spoonfeed so we are the ones that should look for those things. KYC details are usually located on the terms and condition page and TAC are visible before we click on that sign up button.
It's already up to you if you will read it or not but don't just blame the casino after, if you didn't and then the details are already put on there. I think some casino ann threads here in the forum, will clearly state if they require KYC or not. You can just read them instead if you don't like scanning their TAC page. Asking to their customer support or forum representative is also another alternative that you can do.
I can not deny the fact that some casinos lack professional conduct, the information on their Ann thread might say one thing while their terms of service is saying another thing entirely, their customer care might tell you that they don't ask kyc meanwhile their terms of service is saying kyc might be asked from the user if the casino suspects anything illegal or withdrawal of a specified amount and above.
I've seen a situation where the user asked the customer care of a casino if VPN was allowed on the casino, the customer care said yes, the gambler went ahead to use VPN, and he was blocked, and when he contacted customer care again, he was pointed to the terms of service where it was stated that the casino does not allow use of VPN from it's gamblers.
So what am I saying?
It is best to always confirm all information from the terms of service of the Casino, that is the only source where informations can not trusted and cant be easily edited.
