Recently I've noticed more people either agreeing with the relevance of that +1.8%/day trendline (the dotted blue one on my charts) or at least a similar one.
For me, putting a little faith into it, it's a reason to be long-term bullish because the price is still roughly, throughout the spikes and crashes, holding to it.
For others it seems to back up their bearishness: the price is ABOVE that line so I should sell.
Each to their own, as ever I post this in Speculation because I do speculate a little on my charts, otherwise it's just as it happened.
