Copy trading is for those who own a lot of money + they don't have time to spend on the analysis and all the trading-related stuff but i am damn sure a newbie or a person who owns a few amounts of money should not try this. As recently in Pakistan copy trading by students from the waqar zaka official was the hot topic for taking wrong trades in volatile market.
If someone has a lot of money and they do not have the time or the interest to learn how to trade on their own then why use copytrading when they can simply hire a money manager which could do the job for them? Now obviously picking a money manager has all kind of issues and pitfalls in which you may fall, but that would be the correct option for those people, in a way those which engage in copytrading seem to want to imitate this dynamic but without having to pay big money for the service.
That is the main reason why I don't recommend to put your money in fund manager because you do not have full control in your investments. There are a lot of safe proclaim fund manager who's faking their identity to steal the money of their investors. There are also some instances where they purposely lose the funds that they hold. It is possible to make money from investing in fund managers but the risks are too high because finding the right fund manager is not easy. It is really hard to find someone who have a good skill in managing the funds.
I prefer to do copy trading than investing in fund manager because you have more control on your assets on it, there are some fund managers who have strict rules and condition where you cannot withdraw your funds immediately.
