The Winklevoss twins are now among the world's first bitcoin billionaires

The Winklevoss twins now have an undisputed achievement to their name.

Cameron and Tyler Winklevoss are believed to be among the first bitcoin investors to pull in a billion-dollar return after the cryptocurrency’s value surged to nearly $11,500 on Monday.

Once derisively referred to as the Winklevii by Mark Zuckerberg, the brothers are best known for suing the Facebook co-founder and CEO over credit for the idea behind the company, a conflict famously dramatized in the film The Social Network.

The twins invested around $11 million of their $65 million payout from that lawsuit into the fledgling cryptocurrency in 2013, one of the biggest bitcoin bets in the world at the time. That foresight has now paid off handsomely as the cryptocurrency's price has ballooned nearly 10,000 percent in the time since.

The brothers have also sought to channel their bitcoin enthusiasm in other less successful ways. They’ve spent much of the last two years attempting to launch their own bitcoin exchange, a dream that was dashed by the Security and Exchange Commission this spring in its latest regulatory hurdle.

Tyler Winklevoss has even gone as far as to claim that bitcoin will ultimately be more impactful than Facebook.

"Bitcoin potentially could be more impactful because being able to donate $0.50 to someone across the world has more impact than potentially sharing a picture," Winklevoss said in a 2014 interview with The Guardian.

The Winklevii’s bitcoin wallet is among a very small handful to have reached the billion-dollar mark, according to The Telegraph, one of the others being the currency’s mysterious inventor Satoshi Nakamoto.
