Thanks for your valuable comment.

Did bittrex really add HIVE token to it's exchange?

Bittrex made the announcement on their Twitter account.

Why would you assume such a huge price?

I assume this idea remembering Steemit in its beginnings.
Hive is booting with a pre-established user base. These users already have the years of experience gained at Steemit. Therefore, this new blockchain would not have to go through that period of growth and consolidation. I just guess.

... currently common 'enemy' brought some powerful people together.

I have had this thought for weeks.
I once read a definition of Fascism. There I was able to know that one of its main characteristics consists in the creation of an internal or external "Common Enemy", in order to consolidate the union of the people.
Maybe we are seeing something similar?
