You were certainly right about August. I just checked:
Aug 2014
Aug 2015
Aug2016
Except for 2017 (all August seemed to be profitable).

There is a certain truth in numbers and as you said in the video that this thing turns around so fast that it will leave our heads spinning. This month was bear and maybe next few will be as well. But the simple truth of crypto's history indicates that the whole trend has the potential to turned up on its ass - bear today but bull tomorrow.
