The Winklevoss twins, famously known for suing Mark Zuckerberg after claiming he stole their idea for Facebook, are now Bitcoin billionaires, according to a few reports. Cameron and Tyler Winklevoss won $65 million from the Facebook lawsuit, and invested $11 million of their payout into Bitcoin in 2013, amassing one of the largest portfolios of Bitcoin in the world — 1 percent of the entire currency’s dollar value equivalent, said the twins at the time. Their slice of the Bitcoin pie is now worth over $1 billion after Bitcoin surged past $10,000 last week to now trade at $11,100, according to CoinDesk. The cryptocurrency has surged over 10,000 percent since the Winklevoss’ investment, when one coin traded at around $120.

"If Bitcoin is a better gold or seen as a type of gold-like asset, then it could be in the trillions on a market cap," Tyler Winklevoss told CNNMoney in 2015. "We do feel those are very real possibilities." The twins have never sold a single Bitcoin, reports The Telegraph, noting that only a handful of Bitcoin wallets hold more than $1 billion worth of the cryptocurrency. One of those wallets belongs to the mysterious inventor, known only under the pseudonym of Satoshi Nakamoto.
