Snacking on some cashus, these are not mint flavour 



Historically, inflation was defined as an increase in money supply, i.e. money printing. The current convention among mainstream economists is to use a price index such as a consumer price index (CPI). Long term average year-to-year CPI in the US has been around 3.9 % since 1970 (or 3.2 % since 1913) while the money supply has increased 6.8 % yearly in that same time frame. The reason for the difference is the deflationary nature of human ingenuity and technological progress. Based on those numbers, things would have gotten approximately 3 % cheaper each year had the money been noninflationary.
So in 8 years, when the fair price of BTC hits $1M according to the model, CPI is projected to be 36 % higher than today if the trend continues. CPI varies a lot from year to year and that is just the expected rise in prices (ignoring all the flaws in that metric which is a whole other discussion) in that time frame. A big print by the central banks would obviously push the number higher in the short term but on the other hand technological progress, such as advances in AI, will push the number down. Anyway, assuming the long term average, 1 BTC in ~8 years should have a price tag of $1M and it will buy what $640k does today. ~5.8x value increase in 8 years or almost 25 % yearly inflation adjusted. For comparison, the S&P500 index historical CPI adjusted growth has been 3.9 % since 1970.
