Whale take another whale for a trip to the end of leverage. 1 whale shorted to caused panic. Bigger whale bought his short and pushed price to make him rebuy.
Way too many people thinking about whales moving everything when whales follow the trend of a market just like everyone else. Even if entities like the Mt.Gox fund controller is around, he is doing the opposite of trying to make a big splash.
We have whale investor and whale speculant. There are whales with houndreds of milions slowly investing fallowing trend and short term speculats puting dozens millions into shorttime trade willing to cause panic or euphoria.
For example to break 6k to cause panic. I've personally met person who speculates on DAX (
https://en.wikipedia.org/wiki/DAX) on 1 day period (for example he shorts at the opening causing red dildo to scare others and rebuy at the end of session). These are trades where you can, in 1 day, earn milions or loose milions if you will be driven up/down by bigger whale.
