If rumours are true and there are some whale dumping 1000's of coins on major exchanges, then we are going to see a slight decrease in the price of bitcoins, until the market absorbed all those coins. 

I cannot understand why a whale will intentionally want to crash the price, by doing it in this way. I would have rather used OCT trading with more privacy and zero slippage, but I figure this person wants to intentionally hurt the price. 

It would be sad, if this was true.
