I think it is a type of competition system , like we can see in another field where any type of the rumours they spread to amke Thier own profit and also any type of stupid thing they can , similarly here the same thing happening in the cryptocurrency. As most of the miners as well as most of the bitcoiners crowd is from the China , so here we can expect that there bitcoiners trying to bring new new negative things to make the bitcoin and another altcoins to get dump and after that make buy and make profit with small up , well here we should not se towards the negative news because negative news coming and going are now a usual thing for the bitcoin , so don't care much about them .
