The truth is that I don't like using copy trader feature on any of those brokers or exchange, because if I can't be confident in my own trading strategy, then I see no reason to trust the copy trader as well. Well, some people say it works for them, but the thing is that as a trader that I am, I know that the dynamic nature of the crypto or forex market makes it very difficult to accurately determine the direction of the market. As such, I just prepare to go with my trading strategy so that if I lose, I will learn from my mistake, correct the mistake, and go again. "Ones a professional trader, many times a failure." If one can not trade and learn from their errors, then they can't become a professional trader, perhaps those copied trades are also shared by some traders who claim to be professionals.
