Well, I have an opinion that I don't care if it's Chinese, or if it's from any other country, I can't deny that a casino that doesn't have KYC requirements catches my attention, but it's something very risky, usually they are casinos that don't they have certain licenses and their authenticity is really debatable and debatable due to the order of things. If we start to see, currently the most famous and most reliable casinos require KYC and this is undoubtedly a guarantee of being able to protect the security of our data and in turn our money because it falls within the framework of legality, and any claim or closure, because they respond for our money.
You are here in crypto space so don't blindly believe that having KYC'ed is equivalent to security of your balance and your personal data.
How can you explain those hacked casino, exchanges, or etc that require KYC? Did they protect you especially your privacy? No. They just tell you not to worry, and just apologize and they will work hard so it won't happen again, that's their line. Then later on you will receive lots os spam messages.
A hacked/leaked personal information is more harmful than getting robbed.
Even having KYC'ed doesn't mean make that you can withdraw your funds so easily. Look at those complaints in scam accusations, casino, exchanges that ask KYC then lately blocked the account.
Again, KYC can't guarantee you that they will protect you or help you when a hacked happens, or mostly when you are blocked in a casino.
KYC is just legality only, don't misunderstand KYC for anything.
Here the OP raises the issue of gambling platforms without KYC for Chinese citizens is rather related to the fact that gambling is prohibited by law in China and a player who has passed KYC primarily risks his freedom, so you have to prioritize one way or another: do you risk only money or risk your freedom, the choice is obvious, as it seems to me.
