Allowing underage kids to use my details for KYC is the same thing as enabling them to gamble which I know is not good for them. I know the temptation to do that is high especially when such a child have won something big but I will try to resist such temptation unless maybe the KYC is needed to allow him withdraw the money, I might change my mind but I will follow him closely to guide him so he wait for the right age before gambling.
