No matter what we say about fiat, the reality is that we need fiat for our daily living like paying our utility bills, grocery and more. This is true that fiat loses its value over period of time that is why we must refrain ourselves from investing in fiat like saving fiat in bank saving accounts. If we talk about Bitcoin then it is a digital asset that increases its value over period of time and its an excellent choice for someone who wants to increase value of its fiat over period of time. Bitcoin and fiat are two separate financial systems that have their own importance in our lives.
Exactly, fiat currency is actually very important in our lives just as Bitcoin. It's not going to be that easy to eliminate fiat currency from our lives. Some people consider it to be a tradition that cannot be forgotten, and till date some citizens find it actually very difficult to place their trust in Bitcoin because they are only familiarise with fiat curency. I doubt if the government is going to accept these new innovations and accept the idea making cryptocurrency legal tender. One of the reasons why they will object it or oppose the idea is because of its decentralised nature, and its peer to peer operation, the little interest that the government is receiving from the government banks may not be possible in the world of cryptocurrencies.
