Not that I made myself rich by this, but, when asked by noobs "How high can bitcoin go?" I told them it was roughly analogous to gold. So bitcoin and perhaps a few other cryptocurrencies could, in total, come to within an order of magnitude of the total market value of above-ground gold. That means a $10,000 bitcoin is plausible, but definitely not guaranteed. Whereas a $1 million bitcoin is unlikely because something would have to happen to make it plausible. Being somewhat analogous to gold would not be enough. The plausible values for bitcoin are supported by more than "animal spirits." So are the limits to plausible values.
