No. Bitcoin has way to much vortality to be used in Argentina. You think 20 % inflation is worse? Try 90 % over the last months. And now it doesn't matter that it went up there before because most people can't sit on their money until "its up" again. $ is king in Argentinia.
Bitcoin is more stable then Argentina's peso. It is also not subject to the control of argentina's government which has a history of not making good on it's promises to repay creditors.
