The whole thing is it is very difficult pump and dump since there's no enough coins for anyone to own. And selling (dumping) is not profitable once you own enough to start master nodes, which will pump out money. So to recap, the coin is becoming more scares (only 15million mined), thereby more expensive, and master nodes will be rewarded massively with the price of coin moving up. So whales won't wanna dump it at all since it is a cash cow and you'd have to be mentally ill to not want to print money.
