Unlike fiat and gold whose supplies inflate continuously, Bitcoin's has an end. And if Bitcoin remains relevant a hundred years from now, its value in fiat must already be staggering.
gold is limited but we just might have not discovered all that there is in the world but we can’t really create any more gold than we have but fiat we can always create more it’s unlimited so i do not think they are similar
bitcoin and gold are both limited in supply that’s why they are considered good investments
