You don't just pick one and go with it. First of all, I don't really know much difference between "investor" and "holder" but in general, you don't have to just pick one. I hold long term but I also trade a bit at the same time, not with all of my money, most of my money is on long term holding, but that doesn't mean I use a bit of it on trading, that has to be something to care. Which is why I believe that the best thing to do right now would be just focusing on how to get better results, and whatever method you use to get there is ok, there isn't really anything wrong with that, just be ok with it.
