I don't think there is anything wrong with that thought. If casinos are doing the KYC then they are abiding by their jurisdiction. Secondly, if they are doing the KYC then they are also making client-user contracts and it becomes one sort of evidence that we are registered on that casino, we have our cashier account too. As we move with time and make transactions they are getting recorded against our KYC so it's solid proof. Now, you never know when this proof will become an important thing in your life if somehow they do a scam of some type. This could be a lifesaver. I have seen peeps fighting for their life when some casinos ask for the KYC because if they have surpassed certain limits of transaction/winnings.
If that is the case then I hardly think the anonymous nature in a casino matters. I can understand when it comes to the physical one, but when it's an online casino, you have to be very cautious.
Look, KYC is a complete waste of time and rubbish. The real kicker, though, is that it's really necessary, especially for online casinos. You make a valid point when you say that casinos abide by local laws. Scammers abound, and the digital world is full of potential traps. The system as a whole would be significantly more exposed without KYC.
Each time a user registers on one of these sites, their purchases, winnings, and other actions are associated with their identity. You're also right on the money when you say that this proof could be valuable in the event of a hoax. Although anonymity may be in, the trail left by KYC may be the only thing standing between recovering stolen money and saying a heartbreaking farewell.
Casinos online arent like picking candies from a shelf in a store. They could be harmful, complex, and vulnerable to fraud. And even if I despise KYC with all of my heart, I cannot discount its significance in providing a risk-free gambling environment. Therefore, dream on, those who believe they may gamble online anonymously!
