Social medias has billion of users, ( facebook has 1.89 billion users as of February 2017 ) making it the most populated social media. Now we're talking about the big things. This sites make the worlds communication much easier and reliable. There are countless Facebook groups and pages that is related in cryptocurrencies not mentioning all the group chats that are being used as a communication. The technology is there, the thing is that these things are in private, if we're talking about business ideas, it is chronic in social medias nowadays. The information and the potential of cryptocurrencies are there too, one must just have a research.
I think the best way to spread Bitcoin to people is that when there is a trusted and legit Facebook page. That has the capability to make people believe in it. The credibility of the page and it's image to people is important. We are flooding in information and don't know where to find truth. So if there is at least one trusted page ( e.g. NASA , national geographic ). It will have a big contribution to people.
I doubt if 1.89B are all real people since there are literally millions of people with dozens of accounts, even some people have 500+ accounts lol.
Twitter has 500M users but again I bet 30% of facebook users and 25% of twitter users are inactive.
Bitcoin is there for grab people need to come to knowing it by their own terms, I think one thing many people don't understand is that bitcoin is the first currency (digital/crypto) that no government has any control over it and is accepted by millions and they'll pay real hard cash for it.
It doesn't matter what we do and what we say as long as people can just hear about it for once the rest is up to them, but advertising/promoting is good but only time will help to spread the news about bitcoin and generally the world is not ready yet 2 more generations needed for people first to be fully aware and fluent with internet and online world/technology then to get to know about every game changing technology such as bitcoin.
