Down before up?  Where have I heard that before?

Could be necessary to get down before up, but I am not sure. 

Seems that I have heard those kinds of, "down before up" proclamations on a number of occasions, and they don't necessarily end up happening, even though they are purportedly "necessary," and they may even cause some people to wait before buying BTC, to sell some of their BTC or even more risky, to short with an expectation of buying MOAR BTC, and any one of those courses of action might not play out very well in terms of preparing for the likely more important aspect of bitcoin, which is the "UP aspect," which seems to be an actual thingie-ma-jiggie in bitcoin investing strategies.
