Bitcoin is not the solution. Good HN threads: https://news.ycombinator.com/item?id=7100394 (search for the bitcoin threads)
EDIT: surprised that someone downvoted this comment.

Basically Argentinians love dollars and we are not rational. Also bitcoin fluctuations and the difficulty to buy and sell bitcoins with a local bank account makes the innitiative very limited.
Even if that's true (there are ways, though) that doesn't somehow negate the idea that it would be better for the normal person on the street to be able to use a currency that -- while volatile -- retains its value better than the peso.
The idea isn't that the US Government will step in there and say "Here's some bitcoins use these instead" but rather that the people will decide to end up using them on their own, irrespective of policy.
Argentinians love dollars because compared to the peso they're a "safe" store of value that's not under the control of their government, and because so many people will accept them. Dollars are the de-facto secondary currency not because of policy but because of people. There's nothing that would prevent the people from deciding to use bitcoin or dogecoin or litecoin or argecoin if they so decided in the future.

At the end I can bet you $ 5000 that the bitcoin will be marginal in Argentina in the next 5 years. Do you accept?
