Who this questions are complicated one, because as a man you will something that will profit your children in future, for me it's not a good idea giving your child your personal documents to use for gambling verification, so we need to understand such, gambling is a gambling and it has to do your own decisions and you anything that belongs to you to be use for gambling kyc not your fathers belongs, for me I will not allow my children to use my personal data to verify their gambling platforms requirements, because gambling is not a good thing to put in your child or children
I don't see this question as being complicated because as for me i will give the permission for my documents to be use for kyc after a big win because that is what should be the best thing to do first before scolding your child and let him know the danger of what starting gambling too soon will do to him or her and that doesn't mean you are encouraging and underage gambling, no matter how irresponsible any parent can be no one will ever encourage their underage in to gambling, certain situations doesn't require immediate blame but to solve the problem first and that is what I see in here like the money has already been won.
In such situation I will allow it.
If the gambler had lost his money on the bet, there was nothing I could do, but the loss would have been accepted. Similarly, since he has won, Parents should be given all possible assistance by providing KYC to withdraw the money. After getting the money, he should be better explained that money is not the root of everything. Underage should not gamble. Moreover, what is gambling addiction and how it can negatively affect a person's life. Give an idea about that. Children can make mistakes, but they must be explained nicely. If the parents are angry or upset with them, they will not be able to understand it. In such a situation, they may try to gamble secretly. To get rid of it, it is better to bring them back by explaining it properly.
