Bill Gates drops $51B in one week following vow not to die rich

Bill Gates is parting with his fortune at a much faster rate than previously expected. 

In just a few days, Gates reduced his net worth by a staggering $51 billion—almost 30 percent of his remaining wealth—after recently announcing plans to give away virtually all his fortune in the next two decades. 

The Microsoft co-founder's net worth, which stood at $175 billion on July 3, dropped to $124 billion on Thursday, following an updated calculation by the Bloomberg Billionaires Index.
