It's a waiting game. The dumps and humps are feints, just like in an ice hockey game. You prepare to shoot, wait, prepare again, wait, then shoot. The goalkeeper that is prepared for the deception wins.
i agree i suspect that whales want the remained holders to dump their bag, by torturing them with a long wait and a stable price, to test their patience, some will give up
this whales accumulation phase will not prevail for long
