Interesting view. Yes, I fully agree on that. The media-sentiment can be seen as a contrarian indicator, in some way similar to published retail sentiment (or also media related biases) in fx/commodity/indizes/bond markets.

It would be very interesting to gather informations on the view of market professionals (big specs or institutional traders) and to display this information regularly. I was thinking about using Steemit, as a voting tool, in order to achieve both gathering retail data and the bias of pros (by simple saying whoever holds above X USD in cryptocoins belongs to this group). Over time such analysis could be very interesting. But I guess it would be hard to gain enough participations regularly. Anyway, you are right on this in my opinion. Thanks for sharing!
