I agree with you, because we are equally in need, we need fiat money because we know that not everyone in the world can access the Internet or use the Internet.
Yes the combination of fiat and crypto is the best combination in this time because our society not fully advance and not every people are believe in cryptocurrency use. Cryptocurrency provide a lot of advantages then that of fiat currency but it has some disadvantage too. Cryptocurrency are fully digital nature because of this they are not able to use in those places where Internet and electricity are present. Cryptocurrency are highly volatile then that of fiat.
