I think that social media does influence bitcoin's growth a lot as it makes bitcoins know among people and also helps spreading knowledge about them as how they work and all that.People would be get interested and will try to invest in them to gain profits from bitcoins which would contribute to growth of bitcoins.And social media gets to lots of people's homes and would cause to bitcoins growth.
It brings popularity to bitcoin. They make people know a about bitcoin. This is positive for bitcoin's pouplarity and market depth will go and icrease to higher levels by the way.
Of course it does and it also makes bitcoin to be bad in the media if there are ill minded people who wants to criticize bitcoin's name and status as well knowing that its popularity will give and will upgrade people's way of living. This is a matter of life changing world to a better and brighter one in the future. We don't only think because of money but we also think about the people who cooperate behind the rising success of bitcoin and make even.
