what about Music accessories . make a shop and buy music accessories. like guitar, piano and banjo. you can sell mobile phones, laptop computers, and selling digital goods also a good idea.
I really agree if there are selling musical instruments, because I hoby music san almost all musical instruments I master it .. if sell it by online via hand phone or laptop if it match and as I want I will order it, it really help me and other people..
I think that if the op open a general store where daily use items will be available, and offer to accept bitcoin for shopping there. As all types of people will visit here then he will really get a good response from the people. I am sure through this way he will get confidence and will take more interest in his new business. I think there are already so many general stores where they accept bitcoin for shopping.
