So you are talking about  Hivelly (previously was Ethbits exchange) exchange, I visited this exchange website. I also found a copy trading option there, But there is no trader that I believe. If you check most of the trading pairs, there is no order book, trading volume, Trade history at all. So maybe this exchange has not yet started or people not using these exchanges right now. They are active at the telegram, but they only posting memes at this time. I don't know why people will choose Hivelly exchange for their trade activities. It worst exchange ever I have seen.
