you see this chart is very valuable. it has lots of information on it but it is always misinterpreted.
as you can see on the chart, in the initial phase or the stealth phase the rate of rising is pretty slow. the smart money is in or rather the early risk takers.
the second phase in which the adoption has grown bigger the rate increases a lot more. since bitcoin is global and a lot of different countries are in the world some in phase 2 some in phase 3 i say we are somewhere between theses two phases where the adoption has grown quite a bit so the price rise is much faster than before but since there are still lots of "lack of awareness" we are still in the start of the fast rise and not yet reached the peak.
it may probably be a couple more years before we reach the end of 3rd phase and start the "Blow off phase".
Except that Bitcoin has been compared using technical analyses in the past, and has more often than not beaten or failed to live up to market convention. Of course, over the long term (pre-trade market til now), we've already seen some charts that look vaguely accurate. But that's only looking at Bitcoin price as a commodity/digital asset.
Take almost any other crypto and you'll see wild variations. The differences here are in Bitcoin use and adoption, which surely affect the curves on that graph. As users and adopters start using Bitcoin less to trade and more to practical payment use, I predict a much softer downwards curve slowly approaching, and then following the mean.
If there were a blow off phase, I'd actually expect it next year.
