Musk, who is 49 years old, dropped to second place in the “Bloomberg” list of the richest billionaires in the world.
Musk’s fortune settled at $ 183.4 billion, while last January, he owned nearly $ 210 billion.
On the other hand, the founder of the “Amazon” company, Jeff Bezos, regained the title of the richest in the world, although his fortune also fell by 1.7 billion dollars, reaching 186.3 billion dollars, on Monday.
The two American businessmen have remained in the lead since the start of the year.
Musk’s fortune jumped dramatically after the value of his company, SpaceX, rose by $ 850 million earlier this month.
The value of the company specialized in the space industry was estimated at 74 billion dollars.
The value of Tesla shares has decreased, after it was recently stated that the value of Bitcoin digital currency appears to be high.
On Tuesday, Tesla’s shares fell 6 percent in money market trading.
The comments came just two weeks after the company bought $ 1.5 billion of Bitcoin, and the currency skyrocketed.
Bitcoin has fallen from its peak of $ 58,000 on Sunday to about $ 45,000 on Tuesday.
Despite Bitcoin’s recent drop, the currency is still more than 500 percent higher than its price over the past year.
