The term “whale” is frequently used to describe the big money Bitcoin players that show their hand in the Bitcoin market. The ocean as a metaphor for the market is apt, since one can then extend it to include the big fish and the small fish; sharks; rallies as feeding frenzies; waves as market moves; and so forth. It may be, however, that the term “whale” has been applied to the wrong class of investor because the players described below are truly the biggest creatures in the ocean.
Yeah, if you're curious about something just try google most of the time it would give you an accurate answer. Even I also just knew the meaning of whales in google plus info here in the forum.
Just an illustration but whales is not actually based on number of your token hold but the value it encompasess. Imagine 1price of BTC reaches 1million USD then even with 1btc you could be a whale already. Got it?
I guess this a great list to have a better understanding. Discussion is most likely about exchanges where whales could manipulate the market price.
