Paul, wanna drop some knowledge on these guys? http://www.alt-m.org/2015/12/28/theoretical-fedcoin-meet-operational-nubits/
While I'm happy to see interest in bitcoin among Cato's coterie of fans of monetarism and other forms of heterodox monetary policy, I'm less thrilled that they're focusing on the "Fed-coin" proposal and some bull$hit alt called "NuBit", and that commenters on the post are pushing bitshares.
Since you're a credentialed economist, I suspect they might be willing to host a blog post by you replying to this nonsense. (Although I would recommend editing your existing writing on this subject to something a bit more pithy.)
