Thanks.  I invest all over the world looking for things that have been beaten down so much that they can only go up. Brazil and Argentina fit this idea. The declining currency helps as it makes exports cheap. It is horrible inside as it makes imported goods expensive (and especially bad if you have to import oil). 

Argentina is on my list of countries to cycle in. I understand from friends who have done it that it is beautiful, though they found the roads and drivers a bit scary compared with Chile. They zig-zagged the border a lot. 

Good luck
