📉 - 87% from $1166 to $170 November 2013 to January 2015
The Nov 2013 - Jan 2015 crash was the most brutal because it went on so long - 14 months in all. Towards the end I started to think it would range trade between $150 to $250 forever.
The short sharp crashes are easier to deal with because the psychological pain only lasts a few months. Lets hope the current crash is one of the short sharp ones.
This is exactly the period I have chosen to enter Bitcoin, LoL.

It was not funny at all, I did all possible mistakes except one: I have never sold, especially when losing 87%. I am only sorry now that I didn't buy the dip at that time.
