I think that the lowest deposit can make 5 dollars and one opportunity as you said, but if you want to have more opportunities, you should deposit at least 100 dollars and that's not much money, I think and anyone can buy it easily and start with no less than 100 dollars, it is the smallest capital if you want to get valuable profits, not pennys, traders how to invest 5 or 2 or just bad and want the market to easily take this money, don't repeat the same mistakes.
