If you doubt about investing and if you ask me "Does it worth it", I will definitely say "Yes, it does". Because if you smart enough to make a right investment, patient enough to not panic, and lucky enough to not get scammed, then profit that you will get will cover all the risks. In this business you can get much more then you put in. And it will be much faster than trading metals or money or stocks. Of course there is some cases where you lose. But you may lose even on usual market. So why should you not try it?
