As portrayed in The Social Network, the movie adapted from a 2009 book The Accidental Billionaires, investors Tyler and Cameron Winklevoss are among the first bitcoin billionaires. On Monday, Bitcoin hit an all-time high, beating its prior high from December 2017. This mark is significant for the Winklevoss twins, as it makes them billionaires (again). But according to CNBC, they don't necessarily act like it. “While they both have apartments in downtown Manhattan, they say they live relatively spartan lives with few luxuries,” says Nathaniel Popper, author of Digital Gold, “Cameron drives an old S.U.V. and Tyler doesn’t have a car.” Today, Bitcoin is attracting powerhouses like PayPal, Square, Grayscale, JP Morgan, who are all starting to agree with the Winklevi twins that bitcoin is gold 2.0. Many institutional investors are now recommending 1-10% allocation to Bitcoin, as a hedge against the failing U.S. dollar. The twins bought $11 million worth of Bitcoins in 2013 and soon became evangelists, creating a NYC-based regulated crypto exchange Gemini. Ben Mezrich of Boston Magazine described meeting the twins, "I’ve always believed that if the Winklevoss twins didn’t exist in real life, Hollywood would have invented them." The U.K.’s Financial Conduct Authority recently approved Gemini's application for an electronic-money license, paving the way for the expansion of Gemini into Europe. The twins expect Bitcoin's price to reach $500,000. "Inflation is coming,” they said, “Money stored in a bank will get run over. Money invested in assets like real estate or the stock market will keep pace. Money stored in gold or Bitcoin will outrun the scourge. And money stored in Bitcoin will run the fastest, overtaking gold.” The twins see bitcoin’s market value hitting $9 trillion one day.
