...so if a child who is below 18 years has been gambling without the knowledge of the parent and he or she happensto win an amount which requires advanced KYC to be passed, ...
As a parent to the child, can you allow the child to use your details to pass KYC verification, if asked? And if you do that, does it also mean that you are supporting underage gambling?
If my child were honest enough to ask for that reason, I might agree, depending on the amount. But that would have to be their last bet, and they would need to withdraw using my personal info. After that, I'd probably ask for the account to be closed or forgotten entirely.
Earlier this year, I successfully helped my partner stop gambling after recognizing early signs of addiction, like staying up late just to play, continuing during meals, being secretive about losses but proudly sharing big wins, and so on. I definitely wouldn't want my child to fall into the same pattern.
