As Bitcoin is the only global digital currency for the moment, so it bears all the original sin.

Cameron Garnham is a 25-year-old from the outer suburbs of Melbourne who lives at home with his mum and dad. Here is the phone interview.
 
Interviewer: "So how many Bitcoins do you have in your virtual wallet?
 
Cameron: "Well, I wouldn't ask you how many dollars you have in your bank account ...
 
Interviewer: "I don't care, I'll tell you."

Cameron: "No, no, let's not go there."

Cameron is a self-confessed tech geek who's been involved in trading Bitcoins for about three years, which in Bietnamese (a term just made up) makes him an elder statesman.
 
In that time his only reference point has been seeing the price go from a few bucks to $170. So when asked how high he thought it could go, he said matter-of-fact "It's not inconceivable that it could be $2,000 by the end of the year."
