I won't try to change your mind Xd but i will try explain why. the casino won't get an agreement from any company if they don't do they can have problems, because of money laundering especially with large amounts. If there's no KYC everyone will be able to deposit and withdraw no matter what his source of money came from. That's my opinion. Even i kniw it's bithering especially when you can deposit when as much as you can and then get asked to upload your documents in order to withdraw.
But can still also for a normal perosn to be a good thing if it offer more security and advantages passing kyc procedures
If they have gaming license, they have no choice but to implement the AML/KYC protocols.
This is why if there is some suspicious amounts getting in, some of them may ask for proof of funds.
I believe, we can't avoid this to happen these days as crypto casinos are getting regulated by the government already.
For most non-licensed, they may not require KYC but for new ones, it is still hard to trust them especially if you have significant amount of money.
