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?
if you have other coins and your value does not require fiat if trading on cryptocurrency is enough with your coin exchanger and then buy the coins you want for now BTC and ETH are worthy of investment because they have market power.
