Copy trading is not easy as it seems because you have to manage the portfolio yourself. You can only copy the trades but how much to invest in each trade is your own call.
Although copy trading feature is introduced by few of the exchanges but I will still recommend that we should learn to trade ourself and not depend on other people trades.
Previously people used to follow the signals and now those signal providers are providing the copy trades services. Anyways it is my opinion to learn and trade yourself and not become a copy trador.
