Anyone posting this trend is just shooting themselves in the foot because actual TA analysts would see that this trend is clearly trading weakly and likely to fail. You should base bitcoin going up on something besides 'look at this half baked line I drew on the chart of the past 1-2 years'.
But you don't deny that Bitcoin has been bouncing off and/or testing it very frequently off late, and for that reason alone, this trendline and the likely psychological implications of it cannot be ignored?
