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.
One of the most important parts is to realize, diversification and small amounts are not the same thing. If you have 100k, but put only 2k at each trade, that's fine, if you have 2k that is different. This has to be very important distinction. Yes, if you use only 2k that would be very low return, even at 10% you make 200 dollars, and 10% isn't common on each trade, you will probably make about 2-3% at most, which would be 40 to 60 dollars.
But if you do this, all year long, constantly manage to make money then you are going to make a good income overall. Let's assume you do 600 trade, 450 of them are good, 150 are bad, you have 300 good ones, that means 2k+ profited, and you would make a lot better return for sure.
