You can check out Bitget Exchange. they claim to be the world's largest crypto copy trading platform. I have tried it before and even manage to earn some profits from their copy trading and they have a lot of good traders to choose to copy trade from.
I have used some crypto copy trading platform they are not really good indicator, I don't think no one can claim to have great expertise when it comes to trading, you can't always get it right, I started using one bot that have made great profit for people for the past 7 months, but last week after SEC news, most of them loss their money... So trading is all about risky that's a fact you need to accept first before jumping to trading, you win and lose some days.
