Since i joined bitcointalk forum i find it difficult to make a post relating to bitcoin, bitcoin is like physical money (fiat), and i want to know the difference between fiat and bitcoin, and without fiat existence can bitcoin have a name?, after thinking all this with seriousness i concluded that bitcoin and fiat works like brothers and sisters and no one can leave each other, so i want to know if any other digital currency can function without fiat?.
I think that BTC has even more than that and one day it will even replace fiat, by 2050 as crypto experts say. I'll quote "An astonishing 54% of the panel thinks hyperbitcoinization — the moment that Bitcoin overtakes global finance — will happen by 2050".
