Re: "Everyone already knows about bitcoin" no.. no they do not..
Not surprising that they haven't heard of it. None of my family members know much about it either except for the fact that it has some value. The only people who follow the internet news would have likely heard about it. Its very rare to have a new article about it too.
My family members now know about it because of me - I see this as our duty, to inform and educate those nearest to us. I'm still the only one who hodls any though
