To be fair, fiat has been around for hundreds of years and we have used it for so many generations, even though it has many problems, it is still useful in our lives. I know bitcoin has many advantages over fiat in many ways, I am a bitcoin investor myself but I have never compared them and brought the bad things of fiat to denigrate, smear it because I still use it every day. My life has changed a lot thanks to bitcoin so I am happy and grateful to be able to use both. As long as you know how to use them properly, you will find the two are worth surviving together.
