There are people who have learnt how to trade, practiced on demo accounts for long but have not had the money to try trading on the market, and so they have abandoned trading to try search for money first. While there are others who have too little income, that they cannot profit from the market trading, they are always worried about loosing and because of that they make mistakes with their technical analysis and end up loosing the little money they have. Should trading be exclusive to financially comfortable and rich because of how risky it is?
Trading requires a balance between learning, practice and risk management. It is important to start with the funds you are willing to lose and gradually increase your experience and capital. Trading is far from being the destiny of the rich; rich people always started somewhere, mostly they started from 0 with trading.
