The BTC price indeed may be largely and positively or negatively influenced or manipulated by certain humpback whales(Lol)! It is a regular and predominant thing by the pump and dump group to falsify and create a sense of appreciating price market (or vice versa). The force of the whales dumping their coins could negatively drop the prices further after artificially pumping them up! yes the whale could do something about  the price of btc.
