I've noticed that there are some expert trader that consistently losing after making some huge profit the previous year in copy trading, I think it's because every year the cycle is kinda different so it's hard to predict, some people might excel at some bullish period but just outright went so weak the next bullish period, or maybe is it intentional to make exit liquidity? who knows but in a nutshell, these copy trading aren't really effective means of making trade without knowledge either.

personally I just won't risk it following investment of other people, since I'm already so used to investing by my own and my performance is not that bad but not that impressive either. these copy trading are more suited for people that absolutely have no idea.
