I do not have any experience with cryptohopper.com but I consider that bots are not so profitable as they are advertised. As far as I know robots handle arbitrage well enough but any other market strategies are usually failing. You may try to get your own experience to figure out this situation but I am completely sure that nobody will sell super profitable robots because they would earn themselves instead.
Not true! They're simply giving you the automated tools to utilize in your daily trading. The signal based tools are made to assist with automating certain tasks rather then staring at the monitors all day.
