Fiat and cryptocurrency are the same
To begin with; i will like to inform you that fiats and crypto currency are not the same; they obviously can be used to serve the same purpose; but they are not the same. I say this because fiat in cash or your bank account adds little to zero value if kept for a while or if converted to a higher currency for international trade. Meanwhile; crypto currency is a lifestyle where you can get profits or losses; wealth or rekt;
nothing fiat can purchase bitcoin can't purchase, so no difference between both because all are currency.
Bitcoin cannot be used to purchase everything; because locally, fiats is more accepted throughout the world; meanwhile if you are a digital worker; trader etc; you can ofcourse get reward and payment in bitcoin. Both bitcoin and fiat are currencies; serving different diverse importance to the world
It's via a countries that is not civilised, majority of countries are adopting the uses of cryptocurrency for everything both importation and exportation of goods and service's, OK if someone can purchase pizza with cryptocurrency far back when the awareness of cryptocurrency is little bit in society, while can't bitcoin purchase things in local areas currently, so I really disagree with you because people who are using cryptocurrency is higher than people who are not into cryptocurrency, Try to convince me properly.
