Full adoption means 9 billion customers, so the peak is of that curve is at 4.5 billion users. We're still far to the left on that chart.
9 million is a possible scenario I'll call it an optimistic one.
But if new users stop joining the Bitcoin economy today we would have total adoption, and when analysing all the users, they would roughly fit that curve, with most of the benefit going to the first 30% of adopters.
My thought is Bitcoin is growing and as it grows so should the value, statistically speaking, Innovators Early Adaptors and some early majority generally benefit disproportionately to the late Majority and Laggards.
Given where we are in the Hype Cycle, is there value that will cause early adopters to buy in to the Bitcoin economy?
