Well everything is falling into pieces, there are a lot of good news around, that's why the market suddenly climb up to $9k so obviously there is a lot of interest coming from institutions themselves.

I'm also under impression that institutional money has been flowing even before we make it to the bearish zone, it is just now that is it more pronounced because lots of reports just like this one has popping out. So let's see CBoE though, I'm sure they have been pump as well.
