Here's a question - What was the end game of the guys during the accumulation phase? To pump the price and sell, right? So we see the pump in action. Then there should be the sell/dump. What happened to that?

If I scroll to a week ago between 13th and 14th there is an identical pattern. There is accumulation and then a pump followed by sell: https://imgur.com/a/Hysfc
