I know for a fact that 'uncorrelated financial asset' was in play before it shows up on the chart.

In 2008 things were very close to locking up, and one of the cause/effect feedback loops were that 'letters of credit' upon which much of the global commerce system operates were about to fail.  Should that happen today, Bitcoin (or more generally crypto-currency) could rapidly take over in that role.  I would guess that values could go insane under such a scenario.  Of course crypto would be attacked mercilessly by some, but some of the would-be attackers would also be heavy users.  Not clear how things would play out, but it could be a spectacular fireworks show.
