Great work as always Louis! You asked about arguments against crypto-currency we've heard & I 've heard a number of them: it's "fake" or a "scam". "It isn't backed by anything", "it's only good for criminals", " It's too complicated for everyday people to use"...I'm sure there's plenty. Just like you I respect Shiff in general but I think he's wrong about crypto-cuurency. I'm convinced it is the future of money & commerce. 7-3's!
