Guys! This article and that list of countries is more than 2 years old. Everything has changed since then. The same team ought to make a new list.
The article is dated 12 May 2016 - the date is even in the URL!!
As for people being astonished at the list - they are looking at RISK FACTORS.
Countries which are stable have no incentive to switch to exotic currencies. The vast majority of people in the USA continue to use dollars, bitcoin users are less than 1%.
It is much more widespread in Argentina
because there is runaway inflation in Argentina.
Why on earth would someone in Switzerland switch to bitcoin when the Swiss Franc is solid as a rock and Swiss democracy is equally solid, being 500 years old?
You would only switch if a) you have an unstable govt/dictatorship b) there is inflation in your economy and bitcoin is the only way to prevent your money becoming worthless or c) you have a large black market in your country and you want to use a currency that can't be traced to you easily.
