.. And that is why we have to spread awareness e.g. by ask for bitcoin payment in shops or restaurants and by wearing clothings with the bitcoin logo.
+ routinely social media sharings of course! E.g. Bitcoin news articles from mainstreammedia or blogs. Or just your personal opinion (e.g. talk about our flawed inflationary fiat money system and show how bitcoin make you safe against that)

Here you can download the bitcoin logo as vector graphic for free to get it print on clothings:

Moreover I recommend this very attractive bitcoin pullover:

How are your experiences with wearing bitcoin shirts or asking for bitcoin as payment option in offline stores?

 And which other ways of creating awareness do exist?
