My 11yo DS (soon to be 12) has been interested in dropshipping business for a while and he just asked me to open him a Shopify account so he can start trading. Without me knowing he created his very basic website to sell an item, and he wants to sign up for Shopify trial and start buying Facebook ads (for which he would pay) and is very keen for his 'business' kick off.
He did a lot of reading and a bit of effort and he things all will go smoothly and 'knows' all the risks and because I said no, you are too young, and I don't want to him to waste for nothing, he's now devastated that I won't let him and says I have ruined his life 
What do I do? Should I give in? I congratulate him for his effort but do think he will not sell (is a very generic item) and too young too understand. Also afraid if I put in my card details somehow somewhere I will end up with a loss.
