This bubble burst in 5 days instead of 5 months. ...
My numbers would be that $100 is the new $5 for the following months.
Bubble bursting follows a double exponential rate of decay, which is the opposite of what happened in the run up. Post peak, one would expect the price halving time to increase - thus the first halving from 266 down to 133, then the second very quickly down to 66.5. In contrast to your view, I think that the having time to 33.25 will be some weeks away - if the rate of decline slows down as in a typical bubble collapse.
What is your basis for the growth rate of the bitcoin economy? A linear regression of the log closing price on Mt. Gox starting in 2010 to present suggests a bitcoin economy growth rate of 4.8x annually = 580%. That is a fantastic growth rate, but the market gets ahead of that when doubling several times in a few months.
The bid depth on the Mt. Gox order book hit an all time high today supporting current prices. This was not the case during the 2011 crash (bid depth back then was almost non-existent).
