I think your method might be flawed.... knowing about Bitcoin and buying it even if you know about it.... are no guarantee for it's future growth potential.

A lot of people might know about Bitcoin, but they only listen to the negative things they hear about it. (The media and the movie industry will often link Bitcoin to the worst things you can think of, like drugs and money laundering and sex trafficking and terrorism funding.)

We need people to educate other people about the "good" and "positive" things that can be done with this technology and those things that are done, that are not publicized in mass media.
