Twitter will not have any effect for the price movement because in my view twitter is only a tool to carrying bad news or positive news and back again it all depend on the people who spread the particular news which make the price down or up so if the price starting to dropped we cannot blame social media because people who behind it already make the price difficult to up again
Don't you think your words against your statement? since many famous and knowledgeable bitcoin investors and traders who sometimes express their opinions about what's happening in crypto-world or just give some advice. Moreover, most of the crypto-sites has an account on Twitter which used to spread the news regarding bitcoin. so, we can say; twitter directly or indirectly affects the price of bitcoin as one of the social media.
