Yes, there are no issues when kids are learning to trade, but it would be wise to let him wait few more years till he is a full adult before engaging in actual trading. Don't let it backfire on yourself because if he trades now, the risk is larger and he is still reliant on the money his parents gave him. He needs to comprehend the fundamentals of trading. In order to use his money wisely in the future, he must also have a prior understanding of how it feels to generate money.
