I have seen many people have started their business with bitcoins like mobile recharge selling steam keys , etc and some of them are successful and some are not.
Tell me which business you will open with bitcoins a payment option.
I will take it in real world.
Physical goods like clothes, apparells, accessories or anything under the sun that is demand in your place and it will be sold online. Here in my country, online selling is really on hype today and there are lots of it in social medias especially on Facebook. If the owner of that selling group will accept bitcoin then that is an additional option for those customers while at the same time a small form of bitcoin advertisement.
In the online game Im playing right now, Im selling unbound diamonds and Im accepting bitcoin as mode of payment although only few of the players there known what bitcoin is.
