To be honest I haven't given it any thought to promote bitcoins among the small business owners in my city. There aren't many places where I come into contact with street sellers and vendors. Most shops in my city are big chains which aren't very personal shipping experiences. Over the last 10 years all the small businesses closed down, the only ones left are small tahr away restaurants or kiosks. The kiosk closest to my house is run by an old Indian man who is talkative and friendly. I tend to buy snacks and beers there after work even though it's more expensive than supermarkets. Maybe I should try and mention bitcoins to him, but he is definitely above 60 years old, would be better if his kids could help him with crypto currencies. Then again who would actually pay with cryptos for cigarettes or alcohol there? Most of the regular customers I see there are also quite old and drink a lot of alcohol. Maybe retuning old bottles and getting the money in cryptos could be a way to promote it.
