I tried this last 2020 and it did well at first then after a year my funds were going down and then I stopped copy trading. If you are into copy-trading then I would suggest learning the trading yourself but if you don't have free time to study how the chart goes then just try copying their active trade position manually and make sure to always execute stop-loss.
And make sure that you check the price of the crypto that already before buying and if it's already on gaining profit or losing.
One thing I always stands with is the quote that nobody does it better than you. I believe doing it yourself is the most important part of trading because this time around you have actually mastered not just strategies but also things like risk management which are the core principles behind trading. Copy trading is definitely not going to make you know which set up is high probability set up and a risky one, it is the reason why you see those who pay for premium signals call trading unprofitable because they incure losses.
If you don’t have time to learn trading your self I will suggest you leave it off and then go into investing because trading is definitely for Those who have it’s time even if you want to swing it
