I find this dynamic utterly amazing. Or I find it amazing how epically I fail at basic economics.
I usually post more when the price feed is low. Somehow I find more attraction in it, it does fill me with more of a "stayer" feel.
More so it gives me a better degree of satisfaction using that always less valuable (financially) but ever more significant small upvote I have when hitting that dust threshold requires always more VP.
Addendum: of course, low price feed also adds complexity and to me makes the rewards more valuable on a sentimental basis.
