Really worthful for such store.
Big cities have much more competition and is full of opportunities so having a bitcoin shop will result in popularizing the cryptocurrency and when we will have more member in bitcoin we will have more scope to earn.

Well as a new member of bitcoin I can still guess that the minimum bitcoin user is of the age between 16 and 23
Because old guys don't know much about bitcoin and I think many be one or two guy will know about bitcoin. So in my opinion average age will be around 20


Because in my country maximum user are around 18 years or below and old guys don't even know what bitcoin is.
