It's hard to imagine what to do with that money, but Gates knows how to make the most of it.
Bill Gates has a number of passions such as private plane shopping, and a luxury car collection. However, these things only account for a small part of his huge fortune.
He and his wife Melinda have previously said that instead of spending billions of dollars on themselves, they should donate that money to charities through the Bill and Melinda Gates Foundation. They also pledged to give away most of their assets through Giving Pledge.
He has invested in various stocks and assets as well as launched a $1 billion investment fund, Breakthrough Energy, with 20 other companies.
Gates is said to own a Bombardier BD-700 Global Express worth $40 million and can accommodate up to 19 people.
Gates also spends a lot of time and money on real estate. This is a villa in Medina, Washington. It took him seven years with $63 million to build it.
With an area of 66,000 square meters, his house is worth about 125 million USD today.
In 2017, according to the public records, he paid $1.041.292.55 in property tax for this house.
This is a painting that Gates bought for $36 million in 1988.
Gates paid for sand imported from the Caribbean to surround his house.
After founding Microsoft, he bought a Porsche 911 supercar and Bill Gates for auction for $80,000.
But that is not Gates's last Porsche. He also has a Porsche 959 in his car collection.
Gates' real estate portfolio does not end there. He has invested heavily through his personal investment company, including part ownership of Charles Hotel in Cambridge, Massachusetts.
In 2013, Gates paid $161 million for a Ritz-Carlton apartment in San Francisco. As of 2014, it has been reported to be worth $200 million.He also often takes his family to the Mediterranean on the Serene 439, a yacht chartered by Bill Gates for $5 million a week.
