This week, we’ll be hearing from a panel of writers and innovators on the often talked about, but rarely understood, Bitcoin. New York Times reporter Nathaniel Popper, whose book “Digital Gold” tells the story of this trail-blazing virtual currency, will be joined on stage by Gavin Andresen, the programmer who has been leading the Bitcoin project since 2010, and Fred Wilson, one of the biggest venture capitalists backing the project. In a conversation moderated by New York Times columnist and CNBC anchor Andrew Ross Sorkin, this group of powerful thinkers discusses virtual currency and the future of money in the digital age.
