Well, maybe bitcoin can be an alternative to fiat, but i also think that it will not replace. There are so many things to consider in bitcoins, such as unstable prices. It may be very difficult if bitcoin replaces the fiat.
Indeed, bitcoin is an alternative currency and dedicated to online used. But locally, fiat is very useful and I don't think it will ceased to exists in the future. Also in addition to that, not all people are tech savvy enough to used btc and adoption to some maybe slow.
Bitcoin cannot replace fiat, and even tech savvy too were unaware of bitcoin. I too encountered it when I made a conversation with IT professionals who are not at all known about such an existence. When I described it to them they started to know more about it technically. So it takes time for bigger adoption from common people.
Yeah , Totally true , here you can see that Fiat like usd is international currency but still Everyone no using it but btc is not international Currency ( but can be use at international level ) but still we buy or sell or make trade with the bitcoin Only just for the Fiat Only .
Not only in the bitcoin but also in the many other trading profit of cryptocurrency gave the greediness to get fust ( in the last ) .
So this is impossible to replace the Fiat .
But probably if it is possible that the whole world accept the bitcoin legally then everyone will.ske earning and deals at the international level with only bitcoin and we will don't need of any type of the Fiat like doller or anything else .
And we will make buy sell goods with the bitcoin payment only .
