Skills,knowledge should be connected with your emotion too because everything wont really be piled up if you do only focus on some factors and not as a whole.
Actually, isn't the whole point of professional trading to be ensuring that emotions is disconnected from knowledge? I don't trade but if I apply what I know about football, which I also bet on, then I know most of my bets are emotionally connected and therefore, biased.
The same if you are trading Bitcoin and hodling at the same time. If your belief is that Bitcoin will succeed, maybe you are buying on knowledge that is contaminated with belief.
