Mentalities are beginning to change based on some parents incompetent decisions for determining savings for their children and increasing the potentials of maintaining generational wealth. It was the long days were parents are covered on how to raise children to independently raise funds and grow wealth on their own, presently everything differs, parents are becoming the sole creators of this wealth that is to be transferred to their children. The misconception is to figure on which manner at which this capital can be cycled without losing it's value to further the prominent lifestyle of their children and Bitcoin has deepen into the picture as the safest.
Growing wealth is much difficult as time passes, anyone trying to link generations into great finance will have to work the steps up at this moment when the narrative of future endowment are kindled to digital attachment, mainly education are not supportive enough to give that striking establishment that could serve a life time and be later passed to offspring, investment in Bitcoin is just a preferred example of what should be implemented to achieve that financial security for the older takes.
We can say for sure there is a lot of work for any parent who would try to do things right, especially if he is going about the whole process differently to others - but I am sure that as time passes, as you say - the practice that you shared may become more relevant and appropriate for many others.
If a parent understood Bitcoin and invested in it - he would surely want his child to understand it too.
