I highly doubt that JS will try to pump so much STEEM to be again behind HIVE, that means risking money without a good plan to have profits. Anyways if he does there will be a lot of speculation with STEEM and woudn't be sustainable. Imo is way better to take out all the STEEM you have and investing it in another thing. Not necessarily in HIVE right now because is very likely to go down a bit again.
Anyways is hard to know what the prices of both chains will do. HIVE is in madness mode right now.
It's just that feeling I've got "he must have a backup plan..."
Yeah, I thought the same at the beggining of this chain of events, since he said that would move STEEM into TRON but that doesn't necessarily means that he has to pump STEEM. Anyways you're possibly right, you have much more experience than mine in the matter.
The issue is that this guy seems really pissed off with what happened and that is always a bad signal in relation with any bussiness. He has lost incredible amounts of credibility in nearly two months.
Sincerely it would be great if what you say turns to be true, that would allow us to make some profit of the power down.
