I read your entire reply.  I don't disagree with anything you said.

I do think there may be some intermediate solutions on a programmable blockchain with projects like Augur (Intrade on the blockchain), decentralized exchange and currency type swaps.  http://www.bloomberg.com/news/features/2015-09-01/blythe-masters-tells-banks-the-blockchain-changes-everything.

I'm also witnessing the continued clampdown of US government on currency (eBay reports to the IRS on yearly sales for individuals now).  I'm continuing to see it more and more.  This pressure / friction from the governments will at some point force free capital somewhere.  

Cryptocurrency is my hedge/bet on this.  Of the solutions that exist - what do you recommend?  Nothing?
