Where's the best place to do this? Bank, Airport etc? My father exchanged about $10k US in poland into polish money and deposited it into a bank account there about a year or 2 ago and the rate was about 3-1 then. Now the rate is better than 2-1 so if he wanted he could exchange it back to US money and he would make a nice profit. I want to do this myself since the US dollar keeps going down, I feel like my money is slowly burning. Would changing it into Euro's be better than Polish money?
