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.
Look at it this way; come up with a rough approximation of the % of the world population who actually use bitcoin or own bitcoin for each year since 2010, and look at the price for each of those years. If you do some research I think you will see that the price is skyrocketing in relation to adoption, and even today very few people are still to get into it, low single digits I'm pretty sure.
Worrying about where the money willl come from is dumb. Applying any semblence of a linear correlation between price and influx of money is even dumber. Think harder, because you post like a noob.
