I don't think its worth the effort you will be putting to take $1-$3 profit. Sure, it might stack up to some good amount if you keep on doing it, but don't you think it would be better utilization of your time if you do something more productive that will be giving you better profit? As long as you are not selling when you haven't reached your profit goal, everything is fine! Keep holding. In the long run it will pay off.
It is not going to even stack up that much, it is such a low amount that we are talking about basically nothing at that point, who could even make a profit with $1? I mean maybe with $3 but even that is too little, think about all the fees you will have, that means you are going to lose most of that money away anyway, which doesn't make sense. I rather make a big investment and long term so that I could make bigger profits.
This may end up working if you have very very limited funds and you have a lot of time, like maybe some high school kid may try this, at worst they will lose few bucks but that's about it, nobody else should even attempt this. Either put it on long term, or aim for higher profit, otherwise you are spending your time for nothing. Go study something that could make you profit and you will make more money in the long run.
