I think you're mixing things. Argentina elected a new president 5 months ago and that talk was at Davos so he was in office for only 1 month. The "capital controls" and "huge corruption" are things from the previous populist administration. This new president is a huge relief for me as Argentinian, he has Great Vision and Leadership in all this new era for Latin America politics (Venezuela imploding, Brazil crisis, new position for Cuba, etc).
Well, hope dies last... of course it will be difficult to beat the economic destruction of the Kirchner regime.
Bitcoin is really well accepted here btw, there are already some bars, taxis and stores that accept it. The majority of them uses BitPagos that is an Argentinian enterprise that is making the process of accepting bitcoin a 5 minutes thing, awesome for small companies and freelancers.
It's great to hear reports from people, who are actually residents of a country mentioned in media reporting. There have been so many fake stories about international Bitcoin progress that I'm very hesitant to believe in any of these stories without credible confirmation by an insider. So, thank you!
That said, the Bitcoin Market Potential Index appears to be a totally artificially construed index, whose applicability to real world Bitcoin adoption seems very limited to me. I would argue that general penetration of information technology (esp. the internet) and average individual wealth are much simpler yet much better predictors of Bitcoin success in a country. It seems not realistic to me listing Sub-Saharan countries at top ranks that have very limited and/or expensive internet access.
ya.ya.yo!
