This week our guests are the hosts of Coin Talk, a podcast about Bitcoin, cryptocurrencies, and the blockchain. Journalists Aaron Lammer and Jay Caspian Kang talk to us about their show, their own adventures trading crypto, and the weird culture of ICOs, conmen, and speculators that Aaron calls “Coinworld.” Listen to The Upgrade above or find us in all the usual places where podcasts are served, including Apple Podcasts, Google Play, Spotify, iHeartRadio, Stitcher, and NPR One.
