Forget about percents and safe things when you speak of forex trading, please. There is no such a thing. Go back to work and get salary every month, that's fixed and safe.
Forex is like fishing, there always is fish in the ocean, but you can not just go and get as much as you want and whenever you want. You have to hunt, you got to be patient and wait for it, and when it comes you should be ready to do everything to grab it. Once it's gone you should not chase it, just wait for the next try. That's how it works. You see fish - you grab it. If you are lucky enough you are fed, if not - you starve.
