Whales, insiders... pick your market and its manipulated, all of them. Wall Street can knock out trillions in a few seconds. The ones doing this will loose interest in the short term. Unlike silver which has been manipulated for 30+ years, and even has some JP Morgan traders now under indictment.
As for Hive there is likely energy to grow the platform quickly now. I see this as a good buying opportunity.
Good luck.
