I think these log trendlines are guaranteed to be broken at some point in the near future (1 week to 1 year).  A new trendline will be established. This happens all the time on a micro scale.

To maintain that trendline, basically btc would have to have a bubble of epic proportions (money influx-wise) and then only have a protracted bear retracement afterwards. I just don't think the log line is sustainable much longer.
