Tyler & Cameron Winklevoss

We're all familiar with the Winklevoss twins: Olympic rowers, sworn enemies of Mark Zuckerberg, the reason most of us first came across Armie Hammer. But the high society Harvard grads were also some of the earliest entrepreneurs to hop on the Bitcoin train, investing $10 million way back in 2012. The returns have been substantial, of course, catapulting them to multibillionaire status. Their now-synonymity with crypto is also due to Gemini, the exchange platform they founded in 2014. (Get it? Gemini? Twins?) It was one of the first crypto exchanges to be legitimized as a trust bank by the New York State Department of Financial Services and it's now dealing in billions of dollars of assets.
