A biography of Tyler and Cameron Winklevoss, this book recounts their battle with Mark Zuckerberg over Facebook and the $20 million in cash plus $45 million in stock they received from the settlement. It follows how a chance introduction to Bitcoin in Ibiza in 2012 led them to invest early in the cryptocurrency. The story covers their involvement with Charlie Shrem and BitInstant, as well as their 2013 investment of roughly $11 million, which gave them an estimated 1% of all Bitcoin in circulation at the time.
