Elon Musk is well known early-investor and the richest man on the planet as of September 2021 until today. He's also a CEO and found many company today like The Boring Company, SpaceX, and Tesla Motors. With his financial assets and wealth, I think he'll sustain his status for a long time because his companies aren't gonna be bankrupt in the near future. He also invested in bitcoins and many altocoins too.
Unlike Bill Gates and Warren Buffet, Musk will continue to surpass them. And he deserves what he now have because of his passion and hardwork, and nobody can question that.
