I'll be in Argentina on business. And I'm a seller of Bitcoin.
So let's say I sell 15 - 20 Bitcoins to the locals. What the hell do I do with a pocket full of pesos (the hotel has specified settlement in USD)?
Spend Bitcoin wherever you can while you're there, even the smaller cities seem to have a Bitcoin presence if you check coinmap.org. Buy any USD you need with BTC once you're in Argentina.
