Risk is always there, and there is nothing wrong with making mistakes or spending your funds wrong, but it's important to improve upon them.
While taking such risk, it's wise to know what you are up against and also be confident to accept the losses that comes afterwards. Some persons are only pressing forward in taking those risk because they are expecting a huge profit in return, they don't tend to think that the market is dynamic and can still fail them if they don't take their time to make an accurate analysis for the market direction. One need to learn from their mistakes and improve themselve.
