In my place of work only one or two people knew about bitcoin, majority does not know anything about bitcoin, personally I have been in the forefront of enlightening and educating people around me what bitcoin is all about and I am convinced with all my efforts more people will know more about bitcoin I am imploring other members of this forum to do same so as to educate more people about bitcoin.
Good efforts, and yeah, people who say that Bitcoin is well known around the world certainly do not know what they are talking about. If you go on the street and ask someone about it, the answer will probably be that the person has never heard of it.
But people with an above-average level of knowledge, especially people who work in technology business, are more likely to know what you are talking about.
