I think it's wrong to compare the national currency and the crypto currency, because the crypto currency is not regulated by anything other than the demand of people and is intended solely for use on the Internet. The currency is always governed by the state and is used mainly in paper form...
And do you think national currencies are regulated? Governments print as much currency as they want without having to ask for the permission of anyone and finally most of the money around the world is not in paper form, in fact most money is in digital form that you cannot touch, so cryptocurrencies and national currencies have more in common than what you think.
