If you don't have much capital to begin with, you can trade with 'contracts for difference'. You get a leveraged payout, but be careful because it's easily to lose your investment if your margin bottoms out. I made some money on plus500 by trading CFD's.
That is too much risky and once the price reach to the margin you will lose everything without chance of getting back the money if the price once again start increasing. Therefore i think that you should always try to do trading with your own money, even if you have a little amount of trading, because even if the price will decrease too much and you still holding your shares you have the opportunity to recover your lost amount if the price once again recovering.
