Elon Musk, with a net worth of $195 billion, passed Amazon's Jeff Bezos today as the world's richest person, according to Bloomberg. But Forbes says Musk is still $7 billion short of the title. A 6% rise in Tesla (TSLA) shares early Thursday lifted the value of its CEO's stock holdings and options by $10 billion, taking his net worth to about $191 billion. A smaller rise of less than 2% lifted Amazon (AMZN) shares by about $3 billion, putting his net worth at $187 billion. Forbes still has Musk about $7.4 billion behind Bezos, likely due to a discrepancy in the valuation of SpaceX, a private company. "How strange,” Musk tweeted in a humble-brag on Thursday, “Well, back to work.” Bitcoin reached a market cap of $717 billion on Thursday, passing Musk's Tesla at $716 billion for the first time, according to Cryptowatch. For only a few hours the spotlight was off Musk, as Bitcoin broke $40,000 for the first time, but he changed that by passing his archrival today. One bitcoin now costs more than a Tesla Model 3, which has been an interesting benchmark to watch over the past few days as Bitcoin goes on a historic bull run. Bitcoin's anonymous creator Satoshi Nakamoto still holds over 1.1 million bitcoin that he mined in the first year, at a time when each block yielded 50 BTC as a reward. This fortune has never moved to this date, and remains one of the world's greatest mysteries. Satoshi's net worth today would be around $44 billion, far less than Musk or Bezos, but I'm sure given the opportunity he/she/they would have re-invested their profits at least a few times. Bill Gates is a distant third at $132 billion, according to Bloomberg. In December, Musk posted a sexual meme as a joke suggesting how distracting bitcoin is to their business. "The internet will break if Elon Musk converts any of Tesla’s balance sheet into bitcoin," said Anthony Pompliano. Peter Schiff, a prominent bitcoin skeptic and gold investor, warned Musk "do not fall for this con."
