I put "volatile" between quotes because it's only ever volatile one way: inflating into irrelevancy.
To me it's simple and all that is needed to go is to look at the message Satoshi put in the genesis Bitcoin block:
"The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"
This makes it clear Bitcoin is first and foremost a political statement.It's a giant middle finger to governments that do always manage, one way or another, to ever print more money and to grow their public debt ever bigger.
That Bitcoin managed to get in this month of October both the FED and the ECB to synchronize publications saying it's time to think about banning Bitcoin shows Satoshi's middle finger worked.
