Bitcoin has been around for roughly a decade now, but people have been working on the dream of an anonymous, digital currency for a lot longer than that. On this week's Odd Lots, we speak with NYU professor Finn Brunton, who is the author of the new book "Digital Cash: The Unknown History of the Anarchists, Utopians, and Technologists Who Created Cryptocurrency." Brunton talked to us Bitcoin's pre-history, and about how and why there was a major crossover between digital currency believers and people who want to freeze their bodies in order to live forever.
