BTCUSD - Bubble comparison and 2011 to present trendlines

A couple of things have bothered me looking at historical trends.
One is that the 2014 crash was much more chaotic. I've tried to display my interpretation of that here.
Also, the longest logarithmic graph is curved: bitcoin.zorinaq.com/price/
This curve has not been perfectly circular and has been flattening out progressively, nonetheless this is an argument for a possibly more bearish scenario than possible here
