I know I would have never even know this was an option for making money had I not found out in class. Most of the really big corporations have departments of people that do this for a living because it can be very lucrative if done correctly. The best news I have learned about this process of exchanging currencies is that many of the websites that you can sign up with to do this offer free trial accounts to help you learn before you invest your money into trying it. You won't make any money in the trial accounts if you do well, it is just pretend money essentially but with the real market conditions. If you do well in the trial account you will know if this is something you want to try on your own.
Benefits to Forex trading are that is can be done 24/7 whereas the stock market is a business hours only exchange. It is 24/7 because it is done with countries around the world so clearly there are countries that are awake and working while we sleep. Another benefit is you are in control of the trading on your account. You do not need to hire a licensed broker to make your trades and charge you fees. Along those same lines, anyone who does any investing most likely knows that some funds require you to own then for a certain period of time or pay early withdrawal fees. You do not need to concern yourself with this either. One last benefit that I would like to point out is the fact that Forex is not really subject to the same kinds of swings in the market that stocks are subject to. Of course if you always buy and sell the same currencies then there will be market swings. But, because there are hundreds of currencies out there, there is always going to be something for you to make money on because while one currency is up in value another one is down and vice versa.
