"Coupled with profitable mining becoming impossible"
Well it is incorrect to state that. Obviously, as the exchange rate increases, mining becomes more and more profitable. In fact, as of today ($50/BTC, difficulty factor around 4.9M, 25BTC/block) mining has never been so profitable in over a year(!) since January 2011 ($6/BTC, diff=1.1M, 50BTC/block)!
