I suppose I should have said 'hyperinflation resulting in economic collapse', but I think my point stands. Look at your examples - except for Argentina, all your examples involve war or de facto dictatorship.

I think it is unusual relative to the number of countries in the world and the time involved. There's a list here: http://en.wikipedia.org/wiki/Hyperinflatio I count 21 examples in the last 50 years, of which half were directly corrleated with the collapse of the Soviet Union and most of the rest were in Latin America, a region with a long history of poor governance.

Of course Bitcoin can function as a hedge or a store of value, like gold historically has. But the majority of people who extol it for this purpose as in the developed world and the US in particular, where the probability of hyperinflation is very low. The closest we've come to a crisis of that kind in recent years is Cyprus, and (again) that's a place with an unusual political problem.
