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?
for future, i think bitcoin will become the most currency that can be used to pay in supermarkets, but its need a time to make it happen and there are need to get approvement from government, at least from big government for many country and then bitcoin can get accepted by more people.
without approvement from government, bitcoin can not be in offline life and there just small people using bitcoin, i mean not all every people in the city, but small community.
