The general investing question you pose belongs in a different forum, but as it happens I am considering investing in foreign currencies for the specific real estate purpose of preserving the real value of the savings I am building for a home purchase, so I’ll comment on that.
I’m looking at far Asian currencies that trade at a discount to their purchasing power: Japan (surprisingly), China, Philippines, Malaysia, Singapore. I am not sure how to do it efficiently. US banks that offer foreign currency accounts pay lousy rates, and some of the currencies are not available. I may buy futures in Chicago.
