So this theory tries to tell us that Bitcoin's price is a result of some sophisticated adoption curve, but from my point of view adoption is largely irrelevant for Bitcoin - most of those who own Bitcoin are speculators, some are short-term speculators, some are long-term speculators, but everyone is planning to at some point sell. So instead Bitcoin should be analyzed as a zero-sum investment game. If more money comes in than comes out, the price grows. This growth incentivizes money to stay and wait, basically a positive feedback loop. But this loop can break if too little money will be coming in and those who were waiting will become disappointed and start quitting.
