The truth is trading need plenty of money, if you use small money then expect to have little return and you will need the virtue of Patience to ensure that money grows from the little it is to a bigger amount. But if you want to make real profit then use a bigger amount and you will be satisfied with your returns. Furthermore, people who use smaller money blow their accounts faster than those with big money. People who have big money to trade can short in their capital, but they will always grow it back and move forward.
Normally in trading, a smaller investment provide smaller return and when the investment amount is more, the return will also be greater. In this case, risk is an important issue. Trader should understand well how much he will invest and how much risk he will accept. In terms of avoiding risk, if a trader does not invest all his total assets at once, but wants to divide his investment into small parts, it is also not a bad idea. Some traders want to earn more profit in a short time, while others want to be satisfied with a small profit with a small risk. Everything will depend on the investors himself.
