How much percentage of internet users worldwide know about cryptocurrencies, blockchain or steemit?

I think this is just too far to reach the tipping point, and every thing that it's happening now on steemit is just like a rehearsal on a restaurant, where they give away free meals to guess before opening to the public.
Trial and error is giving shape to steemit, greed is obvious, but need is bigger, for instance; most spanish speaking people in steemit seems to be venezuelans and to me is "evidente" that they need this not as something they can do on their spare time, but as a main source of hope to get an income and keep connected to the external world. Same case for people of some other countries.

I like steemit as a platform where I can give my knowledge to people that can not afford to pay one of my courses or workshops, but can afford to share it, to upvote it and to to interact for learning, and at the same time I'll be working for that to happen so there I can get an income. Or not!
