I think you're mistaking how little would need to be invested.
I think my dad would start listening to his god-omen stock predicting son after a few missed billions.
"Dad listen, my college tuition? Fuck it. Put it down on Bitcoin in Jan of 2009 and sell on November 9th 2021 for ~$25T."
I'd have over 10 trillion cash after taxes. Literally would have more cash than anyone on earth.
