The Bitcoin Game #70: Michael Flaxman, Securing Bitcoin

Welcome to episode 70 of‚The Bitcoin Game, I’m Rob Mitchell. I’m always wanting to learn things via my podcast, and hopefully it helps others learn too. So when I heard Michael Flaxman on Stephan Livera’s podcast, I thought he was such a compelling guest that I just had to have him on The Bitcoin Game. In this episode we dive into details about Bitcoin, security, and multisig.

While much of a Bitcoiner’s time is spent in the world of digital assets, sometimes it’s nice to own a physical representation of the virtual things you care about. For just the price of a cup of coffee or two (at Starbucks), you can own the world-famous Bitcoin Keychain.
