So, it seems your kid is already in the gambling world and has enough knowledge and skills through which he can win a high amount. However, the payment is pending just because of the KYC requirements for gambling. Well I will not be the father to support my child at such a young age, instead, I will educate him about gambling and everything else, but I won't allow him to gamble before he crosses his teenage years. The reason is clear, whenever he earns money, it will affect his mentality negatively, and when he comes to his actual life, he will have nothing and will be looking for a quick jackpot, which we all know is not easily obtained. So, my advice to you is to take this payment, but only this time, and then keep an eye on him so that he can't engage in gambling again until he turns 20.
