Mark Zuckerberg, CEO and co-founder of Facebook, lost more money than any of the world’s 500 richest billionaires during the social media and social networking company’s catastrophic year.
Yet even though Zuckerberg's net worth has been on a roller-coaster ride recently, he still remains one of the world's richest people.
His estimated net worth is currently US$67.3 billion, according to Forbes magazine.
In spite of his billions, the 35-year-old American reportedly doesn't have a taste for opulent possessions, especially when it comes to cars, clothes, and travel.
However, he does have an affinity for developing his property portfolio – he recently spent US$60 million on two Lake Tahoe properties.
