Big risk will get big result, if you are still afraid faced big risk maybe you will never get big result at your investment or trading, when you try to invest and faced big risk maybe you can get big result with higher of your profit.
Big risk depends on your self and big result depends on your luck. The combination of your self and your luck is a success. If your risky enough then there will be a greater chance for big result, than never trying at all. Your luck has a great dependence in your self. Yes, it might be difficult to invest your money without knowing what future lies, but of course being risky doesn't mean you have to pour a massive money. Just always think that if you failed atleast you have a little for you to continue more until you experience the big result.
