1. I dont know..I was thinking about buying some Euro or Pounds on Ebay..but I am sure there are some currency exchange places or offices around...where you live..i really dont know whats going to happen..if anything i would invest in gold...no matter what happens gold can always be used as universal currency..i am not sure if it is a good idea to invest in foreign currency but with everything there are risks involved just like the stock market..
2. This is a very dangerous idea. But since you ask; http://www.everbank.com/001WorldCurrency.aspx?LinkID=Navigation
