Assuming I can gather 500$ a week from here and there,how much exactly should I invest.
I'm not that greedy and there is no time constraint.
Invest/ trade with only 20% from your fund to start the journey. I don't agree with 50% - 100%, is too much and we can get " panic " if something wrong happen. Invest/ trade is not the easy way to make income, we will try everyday to get the best result and sometimes loss become our friend. Be wise with your money and have a nice day.
