Quote from riskfreetrading:
Someone did better than you (bonecrusher 200%). Could you do better?
Sure, but you didn't ask about ROI now did you. Max out your leverage at a prop firm (offering 50 to 1 or more), and your ROI skyrockets. Then again, not everyone has such an opportunity, so the answer to the question, "How much can you make?" differs for each person (using ROI as the definition of 'make').
