Gaining 50% in 2 years isn't what makes you ultra rich. That's more the good end of the safe bets. Investing in higher risk companies that a growing by over 100% in size each year is how you really accumulate wealth. Admittedly you have to do it with much smaller companies so it requires a lot more effort, but that's why the rich invest in investment companies.
