Nobody buys aggressively 60m+ STEEM from a pool of liquidity of around 120m and a total virtual supply of 367m! Yes, Steemit, Inc. stake has value, and it's much higher than the market price. But...
On the other hand, a rumor about a large scale acquisition like this might allow one to dump more coins onto the market as the demand to buy goes up. Seems a lot more likely. Free money.
This is very likely and my first thoughts.
Less likely, could be that someone is testing the vibes it creates in the community by associating the two blockchains and throwing Jason Sun name in there...
