Show HN: In a single HTML file, an app to encourage my children to invest

Author understands child psychology.

You can't motivate kids by filling their heads with theory. Instead, make the outcomes of their actions visible to them - then they -motivate themselves- to learn how to improve those outcomes. Add in some friendly peer-competition and you're golden!

> As my eldest son’s birthday was approaching, we suggested that instead of asking for physical gifts, he ask for their equivalent in money. That way, he gathered a decent amount of capital for his first investment adventure.

Yes, why would you want a toy or a book? Why waste time having fun or learning? You could instead watch a number go up slowly while you do nothing. Fun for the whole family, seconds at a time!

> Each day, as they watch their small fund grow, they grasp the magic of compound interest — and that, more than any gift, is a lesson I hope will stay with them for life.

This feels like raising finance dude bros and gambling addicts. There is no “magic” to compound interest, no one should have “watch money accumulate” as a life goal.
