Why should it sound good?
Because if you know there is a need to go through KYC as soon as you register, you can turn your back to that casino and go elsewhere if you don't want to do it. It's clarity and transparency from the start compared to being welcomed in and allowed to deposit and gamble, and then you get asked for KYC if you want to withdraw money from your account.
the best way is to get a KYC free casino to use for your gambling experience
That's easier said than done. If you know one that operates in such a way, go and take a look at their terms and read them thoroughly. You will probably discover they have the right to ask you for KYC whenever they want. The list of crypto casino that aren't going to do that is only going to get shorter in the future.
Always make sure to watermark your photos. This procedure will help to make your data unusable when casino databases are compromised.
This is the first time I am hearing someone suggest this. I have never given it any thought, but it's something worth remembering.
