I appreciate this article--some new information to chew on. I don't think anybody actually knows if there's a bubble right now, because we don't have the experience to put a price tag on cryptocurrency fundamentals. Your article brought some new (to me) perspective. Certainly Bitcoin has a track record and brand that are hard to beat, but still so many questions. One thing's for sure: a lot of people are putting a lot of money where their mouths are.
