Maybe I should just get a wallet in his name and start buying small piece on BTC for him every month.
Forget about me for a moment and put yourself in my shoe, I am sure there are family men and women on here, what will you plan to do if you are in my shoes right now?
Some parents do open a bank account from their toddler to save some money which they can use In supporting when the child grows, as bitcoiner it is even more appropriate to do something like this , since it will be something that will be used for the child in the future and bitcoin is more profitable when it is hodl for longterm. For me I think doing such savings in the bank for the future is not the best because of money lose value due to inflation but it make sense when it is bitcoin, when the child is grown-up it can be handed over to the child.
