I don't know how much a Bitcoin will be worth by 2030 but im confident enough to say that by then the dollar either will start losing relevance or will be irrelevant by then. IMHO prcing #Bitcoin in dollars won't make much sense. I'm a believer in the s-curve.

I disagree. I think fiat currencies will exist as long as nation states exist. Bitcoin will remain an underlying asset, For those who know, But will never replace all nation state currencies. Some countries are still doing very well economically. Denmark has a 38% debt to gdp ratio and never adopted the euro. Bitcoin as legal tender or for an asset to add to its balance sheet is best suited for non competitive economies that perform poorly against more developed countries who already have an abundance of resources. There will be winners and losers and bitcoin is best suited for the losers.
