following my experience in the bitcoin , i can say that , the people who try to get some influence on the bitcoin , are the people who are scared by the bitcoin , because of the decentralization ,
   a lot of investors , who works with blockchain into company , try to affect the cryptocurrencies market , because they are afraid by decentralization , and try to disturb the markets ...

BITCOIN is based on trusting between people , not on speculation ... unfortunatly , some rich and powerful persons ( directors of bank etc ... )  can change the market , by speculation and bad informations ... example MR JP MORGAN make some dumping to buy more bitcoin after , he just say something , and investors execute ...
in fact BITCOIN is a very good thing because of the decentralisation , no matter the  price , this is the future , so do not be scared because of pumping and dumping ,
  THE TECHNOLOGY REALLY MATTER GUYS !!!!
