What is your definition of a whale? How many BTCs do you need to have to be a whale?
In my opinion, Whale is what you called to a person or group of people who has the great amount of Bitcoin that can drastically affect the price of Bitcoin or Altcoins if they will invest or withdraw. They can easily influence the price by doing pump and dump whatever they want.
We will be very lucky if they will pump the price that you are invested in and vice versa.
