HI, I share this podcast from an Argentine bitcoin advocate stating that in past conference, a Central Bank official was present and very interested in estimulating it's use in my country.
I must say that Argentina is going through a tough currency crisis due to debt payments that are making Central Bank's reserves go down, which led to strict regulations to acquire US currency (Argentina is the second country, following US, with a US$/person ratio in the world).
I really can't confirm if what this person says is true since I'm not living in Argentina... but a do know that some people are even accepting bitcoins for fancy apartments....
