If you are going to be trading with less than two thousand dollars, then the best thing that you can do is just try to avoid trading for a while, bcause you will be losing a lot of money because of that.
If he is a newbie in trade then you have a good suggestion to him as I also know that he will lose them. If he will have to start then he have to start with a few dollars and when with these few dollars he earn some profit then he have to start the trade with a higher amount of money but he have not to increase his capital at once , he have to increase a little by little.
