If you cannot make money with 100$, you will never make money with 5k, 10k or even 100k. First of all what is your goal in trading, getting rich quick, or systematically making profits? Secondly, if you are making money on a demo account, when are you ready to trade on a live account? Do you think when you are ready to trade live, you are never going to lose? We learn by making mistakes, getting up and correcting them, lose a few times on a live account and you are either going to run away or you are going to find ways not to lose!
