Right now we determine the value of bitcoin by dollars, euros and other currencies, but if we remove all the currencies and use only Bitcoin how we can know what is the value of Bitcoin?
Do we need to use MBTC then?
i don't know how we can determine the value of bitcoin if fiat is not exist, but maybe we can use another thing like gold, silver or other commodity to compared with bitcoin. i think we can be like a primitive civilization that using exchange to make a deal from buyer and seller and maybe we can barter with gold to bitcoin.
