Forex can be potential investment. But it is not an easy investment. Forex trading requires specific knowledge and skills. It is a work of professional. Without being skilled you would lose your money quickly. No matter how big the investment is. Learning requires a lot of time. Most people do not ready to invest their time to learn the art of trading. You also need a good broker. I trade with XeroMarkets. I like their low spreads and instant withdrawal facility. They also have over 77 trading instruments.
