Identical twin billionaires Cameron and Tyler Winklevoss saunter into their empty 17th-floor offices in Manhattan’s Flatiron district wearing designer high-tops, black jeans and matching sweatshirts made by the high-end streetwear brand Heron Preston. The sweatshirts—Cameron’s is red, Tyler’s white—are emblazoned with a NASA logo, which the twins picked because it echoes the space-exploration theme behind the brand of their seven-year-old cryptocurrency trading operation, Gemini. In addition to being the Zodiac sign symbolized by twins, it was the name of NASA’s second space mission—the one just prior to Apollo 11, which put the first man on the moon. “We actually call our employees astronauts,” Cameron says. “We’re all astronauts building on the frontier of money and the frontier of art and the frontier of finance.” Accustomed to finishing his brother’s thoughts, Tyler chimes in:“We feel like we’re on a spaceship, exploring a new frontier.” On this sunny March day, the spaceship is hitting warp speed. The price of Bitcoin is about to reach an all-time high of $58,000 (it sold for $8 in 2012 when the brothers began investing some $10 million in the digital currency), rocketing their combined net worth to $6 billion. Their latest investment, fast-growing Bitcoin lending giant Block-Fi, just announced it has raised $350 million, valuing the company at $3 billion. And the 39-year-old brothers’ hottest venture, digital art auction platform Nifty Gateway, is basking in the glow of a sale at Christie’s, where the gavel is about to fall on the 255-year-old auction house’s first-ever sale of a nonfungible token (NFT) artwork, a one-of-a-kind computer file tracked on a digital ledger known as a blockchain. Nifty Gateway put the artist, Mike Winkelmann, who goes by Beeple, on the map through a series of “drops” starting last year. Before the day ends, Gemini’s custodial business, which houses digital assets securely, will receive a $69 million cryptocurrency payment for Beeple on behalf of Christie’s, making his “Everydays: The First 5,000 Days” the third-most-expensive work sold by a living artist, after Jeff Koons and David Hockney. “The idea of a centralized social network is just not going to exist five or ten years in the future,” Tyler predicts, when asked about Facebook. “There’s a chasm between the old world and this new crypto-native universe.” Read the full profile on Forbes: https://www.forbes.com/sites/michaeldelcastillo/2021/04/05/revenge-of-the-winklevii-facebook-winklevoss-bitcoin-nft-billionaire-revenge/?sh=14b518531572 Subscribe to FORBES: null Stay Connected Forbes newsletters: https://newsletters.editorial.forbes.com/ Forbes on Facebook: http://fb.com/forbes Forbes Video on Twitter: http://www.twitter.com/forbes Forbes Video on Instagram: http://instagram.com/forbes More From Forbes: http://forbes.com/ Forbes covers the intersection of entrepreneurship, wealth, technology, business and lifestyle with a focus on people and success.
