Over the past 20 years, the Bill and Melinda Gates Foundation has spent $53.8 billion on issues ranging from public health to economic development. Some 16% of these funds have been spent on the foundation’s U.S. programs, which focus on education. The rest is spent on international initiatives, including providing vaccines and family health care in developing countries, expanding economic opportunities, providing emergency relief and much more.

Bill Gates has certainly opted for having more influence than money. He also diversified his portfolio away from MSFT and it turns out it was an unwise move. is investments did well; MSFT did even better.
You can't always get it right!
Although he was still right I think to diversify.
When you're dealing with the amount of money he has, I don't think he can be too upset TBH!
