There are some believes that we might not necessary need fiat currency in trading cryptocurrencies.
My question now is If Fiat is completely irrelevant in the world, and gold do not back crypto, where will cryptocurrency derive it value from?
Even if some people think that in the future we will be able to do without the usual paper national money, this does not mean that it will be so. Crypto currency will never exist without national money, it can only walk in parallel with them and never replace them.
