Bitcoin user characteristic I am starting with the execution of internet marketing activities for one Bitcoin gambling site that I owe, and I am trying to figure what best describes owners of bitcoin. 

Are there any demographics information available? What sites / habbits dothe bitcoin user have, where does he browse sites online, is he using Bitcoin for gambling purposes etc etc 

If someone can help with some insights or useful information I thank you in advance.
Luckily you are not the first person trying to figure this out.

According to an online poll, the average user of Bitcoin is a 32.1-year-old “libertarian” male, from a report at ThinkProgress.

There are some realy detailed Demographics out there:
