we are in the early stages of second stage of Early Adopters.
and remember this is not price chart. it is showing only the adoption and how it changes over time. it is slow at first then speeds up and when everyone knows about that technology there is no one left to find out about it!
the price chart would look like an S which is slow at first then speeds up with sharp rise to a high price then slows down and plateaus on that high price and stays there.
