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.
