you can't say you'll never do KYC, because if you look at all services that involve money on the internet these days they're asking people to do KYC.
I disagree. I have never submitted any KYC in any of the crypto gambling sites that I have played in so far and I won decent amounts which I withdrew successfully without any issues so far.
I also don't understand what's on the minds of those minors who like to play in casinos, where do they get so much money to play? And how can parents not find out that their underage child is gambling at the casino? and something I don't understand
They usually never inform their parents and just steal their debit/credit cards in order to play online. Parents do find out later on through their bank transactions or messages or emails.
