Mila Kunis and Ashton Kutcher rejoin the Armchair Expert to explain how they got into cryptocurrency, how a decentralized currency can exist at the same time as a national currency system, and how El Salvador has recently adopted Bitcoin as their national currency. Mila tells them about her new NFT animation show stoner cats, how people can purchase a token to view it, and how it differs from current production models. Ashton explains that the cost of crypto is linked to the amount of energy used to produce it and what fail-safes you can implement to avoid losing large amount of cryptocurrency to hackers.
