If you really want to earn some passive income through copy trading then my suggestion is you can try Etoro where you can also see the history and the win rate of the trader that you want to copy but I do not suggest this kind of strategy to make profits because it makes you a DEPENDENT INVESTOR/TRADER. You do not have any power to buy in right time and to exit in the market. If you became a dependent investor, you will lose confidence in yourself where you prefer to follow the decision of others rather than your own decision. I suggest that you should divide your capital in half first then try to invest the 1st half in gaining skills and knowledge about trading and use the other half for your startup capital account.
