Personal
A person or company that engages in speculative online FOREX trading will examine the value of one currency as compared to another and attempt to predict whether one currency will increase or decrease in value.
Another reason why people change currency online is in anticipation of traveling to a different country.
With sufficient notice, it is possible to change origin currency for destination currency at an exchange rate superior to that which might be obtained if the exchange were to be delayed until arrival at the destination.
