Yes obviously bitcoin is digital currency, bitcoin can be used to buy food, beverages, even bitcoin can to buy property such as houses, apartments, villas. I believe bitcoin in the future can make ease and profit for its users.
Those things are just ideas and they are not totally existing.I also want to see that bitcoin is being accepted to buy those things but yet, we need to accept the fact that we are still on the process of waiting for the cryptocurrency like bitcoin to be accepted by the merchants like stores and also other people so we can exchange our bitcoin into something not only by fiat.
