Even scary to think about this situation. Since bitcoin is a very amazing case, when coins have risen in price from almost zero to today's $ 1,100. During this time you could earn and become a millionaire. Children will not forgive this.
Yes, but who was sure that bitcoin would grow so well? But I think it is not too late to improve and buy coins now in order to become a millionaire in a few years and the children will be delighted.
I think that you need to live for today and not think about all your generations. Let them take care of themselves. They need to give not a material basis, but a moral one. And knowledge. They will take care of themselves
