I'm just going off of the trading volume, and what I would do if I was Sun. He got millions of HIVE in the airdrop and we know he has an account on Binance. The price ran up to a dollar, then Binance opens and tons of Hive were dumped. My guess is that Sun dumped everything he could to get as much as he could while also inflicting as much market damage as he could. It's entirely possible he jerks HIVE around from time to time, but why spend the time at this point. He made millions of dollars if not tens of millions off of HIVE already.
