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.
well i think he asks whether you believe that it has a future and i really doubt that because in my opinion bitcoins are going to take over soon
Bitcoin could rise exponentially in value but it couldn't replace the fiat completely. And in long term scenario blockchain based fiat transaction may replace traditional electronic transaction but fiat will remain for longer term for sure.
