Lol wat??
You don't have to believe in fiat, it exists and it works for day to day transactions. Don't know about its future.
agree. I myself never think to believe in fiat or other currencies. just use what are available to use as long as they're legal, or no one forbids us to use it, or the advantages are not too much.
fiat itself is not forbiden, is legal and currency. so just use it, don't need to believe in, that's all.
you are using your fiat currency because you believe it. i am using my local currency because i believe that it my local currency can really help me. i also believe on bitcoin and hope that it will really give me a good earning.
