* Today's bitcoin / USD High/Low trading price shows a swing of a bit more than 3%
* Today's Argentine Peso (ARS) / USD High/Low trading price shows a swing of 0.1% (Argentina being a country with high inflation problems)
If I were to work in Argentina I would rather get paid in BTC than ARS, due to liquidity constrains. I would probably convert most of the money to USD, EUR o CHF, but I would keep some bitcoin if I had where to spend them.
I believe you are looking at the official rate.
Having said that, even if I was Argentinian I wouldn't hold any significant wealth in Bitcoin.
