Alpalsignals (first.fastsprominerss.com) offers copy trading. I copied a top trader. The copy trades often executed at worse prices than the original. When I asked why they said it was due to latency and liquidity. So the feature is broken or they are skimming. Either way I stopped using it.
Pros: Easy withdrawals|Personal attention|Automated trading options
Cons: Website design could be more modern|Alert system is basic
