If I am an individual with no exposure to foreign exchange risks, does a currency futures exchange mean anything to me?

Yes, it does, if you want to invest purely as an investor. You can benefit from exchange rate fluctuations just as you can benefit by investing in equities in the stockmarket. However, as in the stockmarkets, you also stand to lose money if the price movements are not in keeping with what you had anticipated. Participating in a currency futures exchange is risky, just as the stockmarket is. You should therefore be knowledgeable about the currency market if you want to participate as an investor.
