We're in the aftermath of an extraordinary bubble in cryptocurrencies and the collapse of FTX is a defining chapter of the industry's turmoil. But what does history tells us about the cycle of bubbles and busts? Which past manias are the most similar to what we've just seen? In this episode, we speak with Brad DeLong, an economic historian at the University of California at Berkeley, who is also the author of the new book, "Slouching Towards Utopia: An Economic History of the Twentieth Century." He explains how the FTX saga shares shocking similarities with the story of the South Sea Company, a British endeavor that was at the center of a massive mania of speculation in the early 1700s.
