I haven't tried it, and I don't think I will try it in the future either. Copy trading feels like not real to me. You are most likely to make losses instead of profits. It is not clear what leverage they are using and what's the value of their each trades. Little movements in the market can make huge impact on profits and losses based on how much you invest. They are the big dogs. They are investing a huge amount for each trade. We can not compare our little amount with them.
Also, not every trader shown there are making profits. Each and every trader make losses at some point. So finding the best one is troublesome. Because is crypto trading, past performances foes not determine future outcomes. Maybe they are loosing now but in the future that could turn into profits. Vice versa for profits to losses.

So what I recommend everyone is to do your own research and analysis. Do it on your own and then compare it with the pro. Don't just copy someone else's work and expect for profits. Use it as a learning process. This will give you the best results in the long run.
