Even as I believe this will happen in some.time in the future, I think it is still a question of how much the community as in the general public in the different parts of the globe have come to believe in and understand the blockchain and the overall cryptocurrencies itself. Until the common retail store owner understands this and accept the concept behind cryptos, it will be difficult for a cryptos to be used or accepted as a payment for our basic needs but this is visible sometimes in the future I believe.
