I think you should set yourself a minimum of at least 200$ if you want to see some profits.
So if you did a great trade and you are at 5% profit, this profit will be 10$ which is a nice amount, but if you start with 20$ for example, and you earn that 5%, your total profit will be around 1$.
I wish you good luck at trading, and take in your mind that it has a lot of risk.
He is a newbie in trading so starting small is good for him. He can test his skills with small amount and he can know if he will do good in trading without risking too much money. He can continue to trade small until he is confident with his skills.
