FIAT money is our daily currency which has been existing here for hundreds of years, when crypto currencies like Bitcoin is squeezing their way up to become a world currency and sort. Can they co-exist? If so then what benefits we can get from them, altogether? Not separately.
it can happen very well, and this has great benefits for the community, such as someone who doesn't know about technology can use Fiat, and vice versa, other than that this will help the bank's movement faster.
