Well, it's always recommended to avoid copying other traders and learn trading yourself but if someone has to copy a trader then he/she should only copy genuine traders who aren't risk takers and patient at the same time. Because the lead traders who don't use leverage or use very low leverage are often the ones who help the copiers to earn profits in long term.

Those copiers who want to earn profit should always try to look for those traders that have low ROI but safer trades. I believe anyone copying such traders won't lose so much even if the market dumps pretty badly because such lead traders often use leveraging to minimize losses and make profits overtime.
