One key benefit i see is that it doesn't matter if the market is rising or falling. Investing in stocks in a falling market (like now!) can be difficult and expensive. However in contrast when one currency falls in value, another rises so there are always opportunities to make money.
I personally am taking the position that the US Dollar will continue to fall throughout this year. As the US economy worsens more and more Sovereign funds will continue to move their money out of US Treasuries and into other currencies and investments. This will cause huge downward pressure on the dollar.
If you need some guidance with your trading then using some trading software can be a grat way to get a helping hand. Many such tools offer a money back guarantee if you are unhappy with them. They essentially analyse huge amounts of market data and identify potential trades for you to consider, saving you much of the leg work.
Take a look at the site below, i got going with this.
