ADDED NOTE
The central pink trendline was drawn to EXACTLY touch lows on 2017-09-15 and 2018-02-06, and the upper+lower bounds were designed to account for a 6.4% Bitcoin volatility factor. Like with the regression trendline with 1.5-standard-deviation range, the recent months of data should help to adjust this trendline.
What's funny is that just yesterday, I noted to myself on the chart worksheet what the prorated price increase would look like over months and maybe years. And by looking at that, I questioned when the trendline would need some adjusting to a flatter slope. Sadly, I didn't expect the change to happen so soon.
Note how the projections for the trendline and bounds prorated over time...
> Primary Trendline: $20.15 per day, $120.89 per 6 days, $604.45 per 30 days, $1813.35 per 90 days, $7253.40 per 360 days
> Upper Bound: $21.44 per day, $128.63 per 6 days, $643.13 per 30 days, $1929.40 per 90 days, $7717.62 per 360 days
> Lower Bound: $18.86 per day, $113.15 per 6 days, $565.77 per 30 days, $1697.30 per 90 days, $6789.18 per 360 days
The little more modest slope won't hurt the long-term projection of Bitcoin, as a 6.7-7.7K per year increase seems like a bit too much. (We're at about 5-6K in the past year, just for a perspective.) Again, going to back outliers, that December boost can't be seen as the norm for Bitcoin's ability to rocket in price.
Consider this the last update for this idea. The next few days will determine how much the trendline slope drops, and that may affect my overall confidence in Bitcoin's upward mobility.
But for now, it's just time to lick those wounds from the bears that attacked my trendline channel. All that's left in my camp is a single item of humble pie...
