Here's is an old article on Why Bitcoin Value vs. The Dollar Doesn’t Matter.
https://www.ccn.com/why-bitcoin-value-doesnt-matterSo the Bitcoin value versus the dollar right now is irrelevant, since Bitcoin is not going to replace the “World’s reserve currency” regardless. Ask Bitcoin industry leaders like Andreas Antonopoulos and Cameron Winklevoss, and they’ll tell you the price doesn’t matter. As Andreas once said on a Joe Rogan Podcast, the Internet’s value is not measured in its ability to replace a number of fax machines. So why measure Bitcoin in dollars? They are totally different ecosystems. Like comparing apples to oranges, literally.
Two different ecosystems, it's not about replacing, but not being absolutely dependent. Bitcoin is heavily dependent on the fiat system, the crypto gurus with several thousands of dollars prediction, the cash flow is there, but it's mostly about expectations to withdraw thousands in fiat at a point in future. There is no circular flow of income, for buying Bitcoin, fiat is needed, but again converting it to fiat, there would be no Bitcoin economy, it would be like using unlimited supply of fiat to buy Bitcoin to cash it out for more unlimited supply of fiat.
I guess if the Bitcoin economy grows to the point where it not only acts as a stable store of value, but also a reliable medium of exchange where almost everything can be bought using Bitcoin, it would have an independent value, where the price/supply/demand is decided more based on investments, goods and services rather than fiat conversions.
