Most of them love to do a scare to those who are ignorant to the flow of the price of bitcoin...They are the one's who want to accumulate more and more bitcoin at the wrong time so they want to create a panic so they could buy..
Yes, they only want to make fool the people who dont have much knowledge about the price tragedy of bitcoin and readily start selling their bitcoin upon listening news like that, and in return the persons who create the rumors are benefited.
