If it was a bot that promise a consistent return, then yeah I will doubt that but what he have there is only said to rebalance things up. I think that one is still possible and doesn't sound too good to be true. Some trading bots might be plug-and-play, that even a newbie can get them running but if not, then yeah it needs a good experience to be able to operate and benefit on them. It is okay anyway, if you can't answer his question very well but as long as you still have some insights, that might still be fine. The one that you said of trying it out and see how it goes, is a good response actually if we don't know how things plays out. That should give an answer to us and we literally can find a way on how to improve things later on on our own, if in case things didn't go as planned.

If it turned out to be profitable, I'm afraid to say that they might solo the gains/knowledge but this can be the result of them not finding a better answer in the forum, so there is no need for us to get angry by that. There might still some who are kind enough to do the opposite thing but if in case it is not profitable, usually both types of people are going to let everyone else know it and hoping they can get another help.
