Ok so spent a few hours todaylooking for the Atena ATM machines. Missed the one in Recoleta shopping by 2 days, no answer at bitcoin place on Marcelo T. Alvear and Addidas shop was gutted with no signs of the machine there either...
Might have better luck tomorrow with the cuervas... +7% plus 1% comission to the exchange. I hope BTC takes another hit overnight
