Of course I believe in fiat. I use it daily and so does everybody else. However, I do not believe in the people/institutions that control fiat. It was a lot better when fiat was tied to gold reserves. Now we just create money out of thin air, which will have severe consequences in future.
There's no reason not to believe it's already part of our daily lives and without fiat we can't get the things that we need with our daily living. But the good thing here is that we also have another option and help from bitcoin so at the same time we have chance to use these two types of currency freely.
So, let us know all forget that, we've been benefited its usage, and I don't think that no one is using fiat nowadays. Although, bitcoin is booming now still fiat exists in many ways.
