Thanks to Alexandre Roubaud for visiting us at Legend. As the co-founder of Bitstack—France’s leading Bitcoin savings app, now boasting over 100,000 users—he discussed his career path as well as Bitcoin itself: its uses and how nations are adopting it. We were also joined on the show by Bruno Collin, a historian and currency specialist, who revealed the secrets behind the coins and banknotes we use every day.

The show’s own verdict is on its page.
