Leo starts very Bitcoin-negative, which he usually seems, if you ask me, but Steve almost seems to convince him this time that it could really be a legitimate thing.  Steve is definitely seems to be very Bitcoin-bullish.

They also plug the episode where Steve originally discusses Bitcoin (or at least discusses it in more detail - I've not seen the episode yet) as Security Now episode 287.
