My reading of history seems to vary a little bit from yours, and accordingly, I am not sure about what you mean in regards to the supposed Fed collapse fear existing in 2014..
If you recall late 2013, there was a fed government shut down that lasted about a month - it was actually a stand off that was much bigger than had occurred previously. There was a denigration of the dollar and a considerable loss of confidence in the dollar that went along with that shut down and that stand off.
In that same regards, there was a bit of turmoil in 2014; however, much of the fear about the stability of the feds was resolved with the reopening of the Feds in late 2013, and so by the time 2014, the path for the dollar was upwards. In fact the dollar has been performing way above and beyond expectations for the totality of 2014 and 2015 and even into 2016, based on there has been no real alternative in which folks can invest (outside of dollar related assets), and yeah, it seems that currently the dollar is in a bubble?
And, certainly there is other stuff going on in the world, besides the performance of the dollar, but suggesting that there is going to be a systems wide failure, seems to be pie in the sky, and suggesting that bitcoin is correlated with traditional markets seems to be assuming system-wide failure, rather than the incrementalism that tends to happen. and in that regard, bitcoin does not seem to be exactly correlated to any existing asset, in part because of its paradigm shifting newness and room for growth, and also because it seems to be a different kind of asset that brings something new and different to the table (which is going to cause it to not be exactly correlated with variety of traditional assets, even if some of its performance may run parrallel to some asset classes from time to time).
