I believe that Fiat will still be a long time to live. While there are state and government, will be Fiat. Without it does not do
You are certainly right, fiat will always be here since it is very useful to us. what we need is money and fiat is money and even bitcoin relies on fiat. Bitcoin might be gone in the future but fiat will never be loss in the circulation.
Yeah you are right that fiat is useful currency and fiat is approval by their government and fiat will be survive for always and bitcoin is depend on people adoption if people adopting bitcoin more and more then i hope bitcoin will be survive for long time.
Bitcoin it can be survive for long time but depends on adoption and depends of the investors .. and i think it can be useful until we die because some bitcoins own by other investors some of them are gone or forgot their wallet as sample they forgot electrum wallet private key with 10k bitcoins.. so it will stay long for ever. so bitcoin will still alive for a long time even many people are sell their bitcoin it will never down again back to below $10.
Fiat s our main money and its controled by government made by banks..
