I don't have any children, but if I had, I would teach him about Bitcoin and how it helped his father to achieve some decent financial progress in life.

Also, it's a good idea to create a wallet for savings on his name, so this money can be applied on his future for personal development, although to mine Bitcoin doesn't worth anymore these days.

There is only one thing I get concerned about. Should the father give abundance of resources to his child, or should he guide his child through the path of hard work? I say that because somehow the lack of resources I had at some point of my life motivated me to conquer things by myself. If I was in a comfort zone, probably I wouldn't be where I am today.
