In this case you can really see what happens when a society is in need of a stable currency. In need of something their FIAT currency can't provide. It's interesting to see if Bitcoin can gain traction over there.
How can Bitcoin gain traction, when its own exchange rates (versus the USD, EUR and CHF) are quite volatile? I'd say that Bitcoin is even more volatile than the Argentine Peso.
You didn't get the point.
The Argentine foreign exchange market is very bizarre. There are a lot of restrictions about obtaining dollars and a lot of the different types of exchanges. You have the commercial dollar, the savings dollar, the dollar for tourism and cards, the soya dollar, the stock exchange dollar, and finally, the parallel dolar (also known as blue dollar).
If you need to import something or do anything which envolves sending money outside the country, you have to fill a lot of declarations, cross the fingers, and wait some months. For some reason, the Argentine central bank is currently holding about 5 billion US dollars which belongs to the suppliers of these importations. These politcs results in the scarcity of imported goods and creates a lot of trouble to Argentina's economy. If you're just looking to buy something over the internet with your credit card, the amount can't exceed the 50 USD.
Also, the exchange rate is very volatile. Just scroll down and play with this graphic:

Bitcoin can be more volatile, but some properties of it as currency may be working better than the Argentine peso. And at some point the government will need to end this manipulation of the exchange market, which will lead to a new abrupt devaluation of the peso and serious impacts on prices. There's a breach of 40% between the commercial dollar and the parallel dollar. Argentina's Central Bank lost more than 20 biillion USD in reserves since the currency controls started, in late 2011. This is not sustainable.
But if Bitcoin volatility worries you, gold can be a good option.
