Binance already have their own copy trading. I don’t see any use case of this service anymore since the exchange itself have it without the need to trust the 3rd party services to hold and trade your funds using their software for Binance copy trading.

I just use some of this copy trading feature on Binance many times. The only problem of this his feature was copy traders only become visible once they are making profit already not when they are starting to trade since they need to build reputation first before someone will copy their trading.

The risk on doing copy trading is they might be an exchange inside trader which might give a sacrifice trade for the exchange to have profit on loss trades.
