Predictions like this tend to forget one rather important thing, rises happen because real people put real money in. The bigger the rise, the more real people are required. You can't magic them up from nowhere.
Real people are not predictable and they're extremely conservative as to where they throw their money. The latecomers will be more conservative than the nutters who arrived early.
If there are enough of them then that isn't a problem but nothing happens in a vacuum.
And I don't think the technological S curve can apply to something so complex that requires people to really think. Very few know anything about money. Adopting mobile phones or the internet was a no brainer.
Big & median money and most people are not in the "game" yet
most money comes in at 34% point of adoption ( the early majority ) and again at the 68% point of adoption ( the late majority)
we are currently somewhere between 7 and 13% point of adoption , so we still have a while to go
