New Delhi: US electric car maker Tesla CEO Elon Musk has wiped out a net worth of $ 15.2 billion in a single day. Shares of his company Tesla fell 8.6 percent on Monday. He will lose the tag of the richest man in the world. Tesla shares have been falling sharply since September. Bitcoin prices over the past weekend, however, have had a severe impact on the stock with comments made by Elon Musk that small rival Ether looks big. He made the remarks on Twitter two weeks after announcing the addition of $ 1.5 billion in bitcoin to his balance sheet. Musk fell to second place in the Bloomberg Billionaires Index with a net worth of $ 183.4 billion on the list of the 500 richest people in the world. The highest peak in January was $ 210 billion. Now Amazon founder Jeff Bezos is in first place with $ 186.3 billion despite a net worth of $ 3.7 billion.
