now you buy food, drinks, daily necessities and pay bills using fiat money and fiat currency is a measure of a country's economic strength. so, fiat currency is necessary, for our daily lives and our respective countries...

No one can vividly tell what the future holds in terms of means of payment although it is clear now that digital currencies is taking over. The Fiat is not all about the paper money, there are fiat stored on credit cards and smart cards and phones which also allow for online purchases. What makes the difference and creates uniqueness on the part of cryptocurrencies is the technology behind cryptocurrencies (Blockchain) which stores all verified transactions and makes it visible to all thereby ensuring transparency.
