Depending on what investment program you are joining in.Me i just invested 20$ in my trading and i have succesfully triple it in almos 2 weeks time frame only.If i only have bigger amount then i would make real good amount.Now im trading with almost 400$ in my balance and its been 2 months i think.
I prefer doing trading rather than selling games or game license because the profit is bigger. But for beginner you should start with a little amount to reduce possibility of loss. When you was feeling match with trading it will give decent profit even more.
