What is whale?

Satoshi could be a big whale if he wanted too. I hope that he wont decide to dump his coins on us xD.

He shall not dump his coins. He can spend the coins slowly or invest in bitcoin related business to promote bitcoin further.

Hi guys i just want you to ask if what is whale? im always read that word but i didnt know what is whale?
I thought is it was a big fish. Or its a kind of greediness?

"Whale" is someone very powerful, who can manipulate market like he wants.

It is very easy to check while on altcoin market. But for bitcoin it's very hard to know that.
