@jrcornell - very true of course but you're preaching to the choir here.  Unfortunately those who need to understand this will never see it or not see it until it's too late.

The actual biggest hurdle to it's adoption at this point is lack of usability.  The regulators requiring KYC and AML plug the dam of equity leak from a very corrupt banking system.  It will slow this down, perhaps just long enough for bitcoin or some other altcoins to scale enough to take over.  It's a matter of time.
