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?
How do we get the value of USD today. We compare all other currencies with USD. Same will happen with bitcoins as all other currencies / altcoins will be compared to bitcoin as bitcoin will be the main currency. It has its own value just like USD has its own value.
