What is your opinion: will btc become a currency with which you can pay in supermarkets, subways etc?
Or will it remain a crypto-currency used mostly in the Internet?
in my opinion after some years the market of bitcoin will move in the practical shops also . it can be understand easily with the examples that many cafe and coffee shop accept bitcoin payment in UK .so soon it will also spread in the all other countries .
Hoping that will come true. Still it is hard to believe if you dont see one. It could expadnd the number of bitcoin users by doing that. They will be thinking what is this bitcoin that they accept. That also may be absorbed by other stores.
