There are holder whales and non-holder whales. I knew a whale who owns tens of thousands of BTC, but a non-holder, she sold all the BTC around $14000. And I believe there are many of those non-holder whale and caused bad for the market.
Whales who have sold bitcoin at high prices like 14000$ does not mean that they are out of business. They will buy back again at less price and then again sell at a higher price. This cycle goes on and whales are becoming more rich every day. 150 Billion dollar market is easily to control if two or three whales combine and manipulate the market.
