I don't know what country you're from, but you should consider making it material, with a brick and mortar shop on a popular street. You couldn't make it viable by buying and selling BTC only, but you would help a lot the community by giving BTC a street presence.
Bitcoin is an Internet money, having a street shop instead of an online shop kind of defeats it's purpose, IMO.
Well, lots of people like me want
BTC to move from being Internet only. That's why some install ATMs. Ultimately, I guess it depends on your country, and its people. How do someone buys
BTC where you are? Any local players already?
