Bitcoin is by origin a web currency, and in very early days. Aside from a few fringe examples it's extremely hard to find situations of it being used regionally.
Would be great if it could be used to buy drinks at a nightclub, petrol, or for groceries at the supermarket, but I'm not sure that's the way it will go.
Im thinking of selling "aussie emergency packs" of vegemite,tim tams ,anzac biscuits and coles vouchers (it is an aussie wide grocery store) which also sells alcoholic beveridges and you can use the receipts to get discounts on petrol...
I am one person in an economically depressed area of Australia so if I can see the potential its only a matter of time till everyone else does.
If only I owned a shop I would have a price in bitcoins on the shelves right now .
