The GFC was partially caused by the Federal Reserve keeping interest rates too low prior to the GFC for far too long after the dot com bubble popped. When they finally pulled on the brakes we lost Bear Stearns and then Lehman Brothers and we have been dealing with the fall out ever since.
So arguably if the Fed had not screwed up badly in 2000 - 2006 we would not be here today.
Which makes bitcoin the grand experiment. Of course bitcoin could also succeed and make the rich very rich and the poor very poor due to its deflationary structure returning the world's workers to the status of serfs to the tech elite. That's also a risk.
