Buying some stuff does not make a person a Whale. The term and meaning was described over a decade ago in documentaries and interviews. The biggest spenders, the real whales, spend inherited money from grandparents. In recent years, app accountants set the median point where half the income of app comes from non-whales, and half comes from whales. In some apps the whales contributing 50% of income are under 2% of players, and it varies. In the 2% portion are a few legitimate whales, not many, who buy all there is to buy. So many people perverse the meaning of whale, and some include metrics of participation hours. I just use the inarguable classic definition.
