Twitter is just a part of media like print / electronic or social media including Facebook; linkedin ; You Tube etc. And each type of report on any type of media has effect on the price of bitcoin. When there are positive news the price goes up and in case they spread negative news then the price falls.
Lulz, if it was so easy then we could make 4000 bots on twitter posting 10 positive tweets daily. Then wait to the moon coming to me.
Be real it doesn't work like this. Also, Bitcoin is too big for Twitter, you can post 10k negative tweets on Twitter the price won't decrease.
Twitter can have a relation with a smaller coin but surely not regarding Bitcoin
