The beginning of the cryptocurrency is indicative of a long tail where at a large global outlook (5 years) the trend seams to be fairly steady with no major variations. This is before a cryptocurrency has been extremely exposed to interest from a large audience.
The length of the tail shows that the cryptocurrency has been established for a long period and can be compared against other cryptocurrencies. Bitcoin is one of the first so it will have the longest duration.
Looking at (all) as the duration a small blip happened at end of 2013 where it could be seen that this may be a bull market but slowly dropped off. The behaviour of how this dropped off (bearish market) is also worth to note. This is like a sharp spike then a slow dilution. Could this behaviour happen again?
Since the start at end of 2011 to mid 2017 on my roughly drawn trendline, the price went up from $80 to approx $1100 (+1275% ie x13 ish).
During this whole period, bitcoin and blockchain technology was still being developed, with a few bad publicity along the way. The long tail period is not indicative of where mass interest. This happened at the intersection possibly start of 2017.
