Yes on one side it really is a good idea, letting others know about Bitcoin as well as the cryptocurrency world through the social medias or blogs. On the other hand what are the possibilities that people won't see this as a means of you defrauding them. Sometimes when people see adverts or posts of crypto on socials, they tend to just ignore because to them, it's just a scam. How sure are you, that you can convince the public that you are not scamming them but trying to help. To me it's a good idea ooo but it would be a waste of your time because most people won't actually give ears to such posts.

But if it's what you wish to do then there's no problem trying. There a first time for everything. You can as well give a reasonable Description and important facts, like the prices and other related issues concerning bitcoins. Then take proper analysis on the views and replies you get from each post. So you would have an idea on what your viewers are most interested in the Bitcoin world...
