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?
Good question but I think we can measure it against other Altcoins and even commodities as Bitcoin itself is viewed partly a commodity. So it wouldn't be difficult unless there's nothing at all in this world except Bitcoin even with that we can measure it against the human beings present and get its value.
