I realized that my channel on yesterday's analysis stretched all the way up to the Dec '17 high and that this wasn't an accurate representation of the channel. Here I've corrected the channel to more accurately reflect the overall growth of BTC through the years. This channel tells me that BTC has had average returns of around 150% ROI each year. Which is to say that if you started the year with $1000 in BTC then you'd have $2500 after the 1 year cycle (bubbles and busts not withstanding). We are currently in the middle of that channel so a correction after the long rally that got us here is little surprise.
