You will NEVER make money playing Rohan. You will spend LOTS of money playing it, but never make a dime.
As for virtual money, it is horribly devalued here. But if you really need to make it, farm a lot and sell the best drops on Exchange Market and the crappy stuff to in-game vendors (NPCs).
But don't expect to buy even a donut and a cup of coffee with what you make.
