If we take every dollar in existence and make the existing quantity of BTC equal that amount of value, what will a coin cost in the (now-defunct) dollar?
Just wondering what will happen if a large economy switch to Bitcoin
This will answer your question:
https://cryptovoices.com/basemoney/In summary, if the $6.4 trillion USD base money were replaced by 19 million BTC, then each BTC would be worth $337k.
However, keep in mind that inflation is already eroding the value of a dollar, and I would discount that by 1/2 to $170k in pre-inflation dollars
