As investors ask how China's yuan may challenge the dollar's reserve status, the much larger disruption will come from the cryptocurrency and stable coin alternatives that have exploded on the scene. Christopher Giancarlo, former chairman of the Commodity Futures Trading Commission and self-described "CryptoDad," explains to Christopher Smart why the United States must move quickly to develop a digital dollar that reflects fundamental American values like privacy, innovation, and trust. They also discuss his book, “CryptoDad: The Fight for the Future of Money,” and his participation in the Hoover Institution study, “Digital Currencies: the U.S, China, and the World at a Crossroads.”
