Charles Ponzi's scheme (plus a new scam)

Charles Ponzi’s infamous 1920s financial fraud originated from a simple arbitrage opportunity involving International Reply Coupons, which allowed him to exploit currency devaluation between the U.S. and Europe. Although Ponzi never successfully executed the stamp trading business, he sustained his operation by using capital from new investors to pay off earlier ones, a model now synonymous with his name. Author Mitch Zuckoff highlights how Ponzi’s "big swing" mentality and the era's pervasive "fear of missing out" fueled the scheme's rapid growth, attracting thousands of investors before regulators finally intervened. Beyond this historical analysis, the episode addresses a contemporary threat where scammers impersonate podcasters to steal cryptocurrency from listeners. This serves as a reminder that while the mechanics of financial fraud evolve, the underlying human vulnerabilities—greed and the desire for quick wealth—remain constant, necessitating vigilance against unrealistic investment promises.
