Elon Musk | $178.7 Billion

Elon Musk has made himself known as one of the most prolific contemporary inventors and has catalyzed humongous advancements in technology such as renewable and energy, and notable, space travel. His first notable investment was made in PayPal. He sold the company later on and invested $100 million in SpaceX, a space travel company that produces satellites, rovers, and other spacecraft for NASA. His proliferating ideas are often centered on space travel and environment conservation by manufacturing electric cars in an attempt to curb fossil fuel consumption. His ideas have made significant impacts in both the scientific and philanthropic world. Popular culture often reveres him as a modern-day superhero dedicated to solving modern problems.

Except for materializing space travel and battery-powered vehicles, Musk is an avid follower of cryptocurrency. In a 2018 interview, the entrepreneur once proclaimed that he did not own much in crypto. However, there have been some rumors that he might have investments in cryptocurrency.
