Currencies are an interesting way to invest. It seems odd that you can even use currency to make money. How does it work? There a few different ways that you can do this. Basically, you are trying to profit on the differences in the value of different currencies. The most common way is through a speculative market that relies on a change in value. This type of investment is probably the closest to binary options. There are however, significant differences. Take a look at the pros and cons below to see if currencies, which are also know as Forex, are another option for you. 

If you look at the good and bad aspects of currencies, you will find many similarities to digital options. The difference is in the process, and diversity of what you can do. Forex lacks the simplicity, and easy access. You cannot profit on a variety of stocks, currencies, commodities, and indices like you are able to with binary options. A good way to go, but in my opinion, not one of the answers for a successful investor.
