I've had conversations about this market unpredictability, or irrationality. It's impossible to tell what it will do, but we can make good guesses based on research and then take action.

Right now, I've put a lot into Steem Power, so it's disappointing to see it go down. However, I've already reaped rewards from being able to upvote things I like and getting curation and author rewards. Not many crypo-currencies have benefits like that (in fact, none others that I know of).
