I simply want minnows to be aware and not get left holding this assholes bag.
But you don't even know if he's actually selling. Also, another whale just sent 4x as much STEEM to Poloniex in the past 24 hours. And he has done that for the past three weeks. Why are you not also complaining about him?
Furthermore - who cares if they're transferring or selling? This is going to happen, regardless of price, the amount of stake, and how long they've been holding. STEEM is nothing more than a speculative investment at this point. How do you expect people to treat it?
In any case, having large stakeholders divesting is good for the platform. Distribution of stake has been the single biggest problem with STEEM. We need more divestment - including from the founders themselves, their dev. team, and their friends. None of these transfers are "good" or "bad" - they just are. It's happening no matter how much anyone complains. Just embrace it and move on.
Just one reason? OK...
Maybe to power up alt accounts without everyone knowing which accounts you own.
Nesting limit...
He doesn't need to prove anything to anyone. It's his stake. He can do what he wants with it. In my opinion, you're actually lucky that he hasn't flagged you more than he has already.
