Hmmm; According to which metrics and stats is investment in early startups / random new companies and schemes, the best way to accumulate wealth? How do we define "best" - safest? Highest top possibility? Lowest risk? Over which period of time? Our experiences may vary. I have far more visibility into people scammed left right and centre where I'm at. Those who did make money on sketchy schemes are lucky outliers (who of course believe themselves to be savvy risk takers fair enough ; I see most of them as incorrigible Russian roulette players who got lucky but not wiser).
