By looking only at the yearly lowest dollar value you'll find out that Bitcoin is always more expensive in a given year than in the previous year. On average, its dollar value increases (at least) 325% p.a. on average (2010 - 2018).
Thoughts, ideas?
isn't that how traders do technical analysis?
by connecting these lows to draw support line, and highs for resistance line
the support line shows an increasing pattern means more supporters on bitcoin through the years
why it's increasing? more bitcoin adoptions, more people investing, and etc...
