If I decide not to allow my child to use my kyc then it Is already a big loss because it won't even erase the gambling experience of the child all these while that I'm not aware the child gambling activities.

 I'll release my details for the kyc because the gambling was not played for free and this is just a reward but this doesn't mean I'll be so excited because of the win and that will make me not to tell him the right thing to do. I will still advice him to quit gambling because it is not the right age to embark on gambling.

Gambling do affect underage more because they gamble with low understanding.  At first they see gambling as a medium for money to be made and they now abuse it to gamble without control to make money by all means.
