A while back someone concluded SR was doing about $2M per month - XBT was at about $10 given that SR accounted for over 90% of the economy looking at the money velocity and the available coins it would be reasonable to assume a valuation of $2 per coin. However Bitcoin jumped in value to around $266.
The net take home was Bitcoin is 1% currency and 5% money remittances and 94% a store of value.

It's value is not reflected in the economy but in its potential. If anything I blame the lost year of 2012 to the premature hype created by SR that brought on the June 2011 bubble a few months too soon after rising from $0.008 to $0.08 followed by $0.1 to $1.0

The expectation is we will see a new order of magnitude in evaluation soon. Sell if you must I'm all in this time around.
