As of 4th quarter of 2021, Elon Musk have an estimated net worth of $292.6 Billion and stands on the top of worlds richest person alive.
I think Elon will stay for this spot much longer than Warren Buffet, Bill Gates and Jeff Bezos combined. It's because he's the CEO and founder of SpaceX, owns Tesla and founder of the famous "The Boring Company", he also invested in ETH, dogecoin and probably have the most coins of bitcoin. And also, maybe we can really hear stories from people who keeps trusting his words and following his shadows who will probably sold their assets in few months or years to come.
