I think this motivated seller has something to do with @project7 and @steemhunt. They have clear connections with UpBit and were excluded from the Hive airdrop (so they probably have a lot of resentment towards Hive)
I met @project7 at STEEMFest in Krakow and I used STEEMHunt a lottt. Sucks to see the divide among the community thanks to the actions of a tyrannical dictator
