Argentina is in serious trouble with it's debts, and may now default within the month. The last time this happened peoples bank accounts were frozen (cypress style), and they suffered hyperinflation (still are, currently estimated at 100%). They have a massive thriving very public black market in US dollars.
This default could be the Black Swan event that everyone is looking for. It's impact on Bitcoin could be massive given the generally high level of internet usage in Argentina witha desperate middle class looking to protect themselves (or even make money!) this time around. If I was an argentinian I certainly would not be keeping my hard eardned peso's in any bank right now, and certainly keep them in bitcoin if I could.
