You only need to think a little bit to know this is not a good option, if you have a successful strategy that you have developed on your own will you share that with everyone for no cost at all? What if one of the persons which is copying your trades is then able to realize how are you making your money and then tells to more people making your strategy way less effective? The risks are simply too high with no benefits, so most of those that allow themselves to be copied do not really have a reliable strategy at all.
