Fiat is still used to buy things, so no wonder people have faith in it. It would take dramatic changes like what happened recently in Zimbabwe for people to completely lose faith in fiat, and even then some of them would still cling to it, in hopes that somehow things can return to normal.
Fiat is still used to buy bitcoins in the first place!!!!
Without people using fiat , u got no bitcoin users.
People are buying bitcoins with houses and cars. Don't forget some subways also accept satoshis. Fiat may be relevant now, but bitcoin will be much easier to spend in 2-3 years.
