In a long period of time (like the movement in every year) Bitcoin movement is unpredictable, because at that time what determine it was news, not technical analysis. So the Bitcoin movement cannot be predicted. Like in the last year, a few months before the price soared no one would have expected Bitcoin's movement to be so strong. If you want to predict based on technical analysis then Bitcoin’s price will fall if met with the death cross, I think someone here had discussed it.
