Thought it might be interesting for y'all to see the 'raw interview':
2) Bitcoin isn't the first or the only digital currency, but it has rapidly become the most prominent. What accounts for that?
People trust that it isn't going to disappear, because there is no central organization that can either go bankrupt or be forced to shut down by a government. Currencies are all about trust, and more people are beginning to trust this decentralized currency that is supported by everybody who uses it.
Gavin's answer to #2 is why bitcoin doesn't conveniently fit into Mises' Regression Theorem, which doesn't account for digital mediums, let alone vulnerable ones. I wish more Austrians realized that too.
