That's what Exyle said in the video. But I can't imagine a supermajority of witnesses being OK with that. The whole point is that the Steemit Inc ninja-mined stake is a special case, as up to this point it has been clearly declared on many occasions as earmarked solely for the development of the Steem ecosystem, and to be non-voting in governance issues.

So no, selling it on Binance would not be OK according to a supermajority of witnesses. Check it for yourself:
