The thing I've always hated about your insistence on trying to push this Armstrong character is that you basically imply we live in a deterministic universe.  Even if his models were right (probably not), there are too many wildcards.  Some random oil sheikh can wander along and say, "What is this Bitcoin?  I think I will buy this...all of this", and up it goes.  Maybe all Bitcoin needs to do is hit $1200 and that causes a butterfly effect where governments in the Cayman Islands start buying it.  Anything can happen.  There's always thresholds variables that cause domino effects.

The other fact is that the economy is going to collapse in a black swan event, not an orderly walk to the exits.  There is no sitting around waiting to "buy the dip".
