That's true, and we can get a lot of experience as well as knowledge when we want to learn from a mistake to be a little more advanced, want other people's mistakes or our own mistakes to have the same benefit to be more advanced if we want to learn from those things. And it's also very true, on the other hand we can also take advantage of other people's mistakes for us not to do, which as we know that there are always consequences or some losses when we experience these mistakes, so by learning from other people's mistakes we will minimize some of the these losses and not doing things that could bring us down. I don't think any of them have had any success using copytrading, and if they did I would wonder how they did it. What I know is that when we want to go through various processes in a field with some mistakes that we might experience there it will be more likely for us to get success, I would advise someone especially novice traders to do it themselves instead of relying on copy trading, even if it is very helpful in gaining profits but still it will be very difficult for us to develop if we only rely on other people's knowledge. Learning from one's own mistakes is a more promising process for future success.
