Crypto is a new innovation that was developed along with internet discovery. This is clearly digital technology that can only be used as long as there is an internet network. You can imagine when everyone uses crypto currency, suddenly the internet is cut off due to disaster or sabotage? Of course everything related to crypto stops. Will life stop? No!. Therefore, crypto money is important, but not as important as fiat money. Long-term crypto money still exists, but only applies to certain groups, because modern society is most prepared to use it.
