It seems to have a natural equilibrium. The issue is that it's too popular and valuable, there are people putting too much effort in, so a casual investor won't get into it. If it were less popular and valuable, it wouldn't be worth putting so much effort in, so people wouln't, making it more appealing to a casual investor. The feedback loop seems to be stable.
