As of now there is none despite bitcoin being legalized in our country or is it ? i really dont know if it's accepted or not cause recently the government made some rules and regulations in using it. So i thought i can use it as payment for other businesses such as for example you have said supermarket but it seems there no store that is currently accepting bitcoin in my country.
Bitcoin is not accept in the supermarket. It malt purposes selling so it will use some product only. Bitcoin is not accept some country. So that the reason it accept the bitcoin. Bitcoin is the become future grownup. It will be change prices change every day. If bitcoin accept it will useful to the future become the bitcoin is improve the prices.
