That your first point in particular is what makes me sane. See, one thing is to be investing in a space and the other is to have all the necessary knowledge you need to make the best of it. Knowledge guides us in most part of it and most especially the knowledge of making trading decisions. Bloodbath to me since I learned how to trade effectively, seems more like an opportunity than a problem if you know what I mean. With learning, persistence and good experience, it is always worth it at the end.
However, for those who may find it hard, I guess just sticking with the idea of investing what you can afford to lose to at least douse any unnecessary emotional stress, and keep holding for as long as you want to is the best bet. At least, those were my moves until I found out a better way to take advantage of the market fluctuations.
This is a very informative response. I can't say that I am that knowledgeable in trading yet but I agree with all the points you mentioned.
