Of all the countries that you listed, I am looking more forward to Argentina because by far on the list they are the biggest country to adopt bitcoin, it's not that I do not appreciate the value that the other 4 countries are contributing but the big factor in adoption in my opinion is the quantity, meaning that to truly test the feasibility of adoption, we have to try if it can work with more people on a country.
Its truly helpful to see a list of countries that really accepts Cryptocurrencies as it is and really utilizes it to the fullest. I would also like to add that even though a country is not that technologically advanced, they can try and adopt it on a national level as long as there will be guidelines on how they can use it properly and how would it boost their economic status.
