not entirely true, see that wiggle in 2011 (went to 0.55-0.57), then back down (temporarily) to zero, but only the last two 'bubbles' might be really relevant, I agree.

A corroborating piece: masterluc redid his graphs, which now predict this runup as a "3" with potential high of 50-70k (later correcting to 10-11K).
I can live with $50-70K high  

Second piece: Novogratz suggested in an interview that Fed might become nervous if we rapidly approach 25K. Not sure how they would transmit this into possible action.
