If it doesn’t happen either Bitcoin failed or fiat fixed itself.

If you only assume annual dollar depreciation of 7%, the value of bitcoin should double every 10 year - using the rule of 72. That means the following future values if demand is held absolutely static and no more money goes into bitcoin:

0yrs $100 000

10yrs $200 000

20yrs $400 000

30yrs $800 000

…

It get to $10m pretty quickly (in a lifetime), in a worst case scenario. But then again this kind of price appreciation means nothing if it is just due to dollar depreciation. I expect increased demand, and then pretty soon a point where valuing bitcoin in dollars is stupid.

The Ribeye Steak Index would be a better metric: SATS / 1KG Ribeye.

If you want to really understand if bitcoin is going up in value you need to compare it to something valuable not to something that everybody agrees is printed out of thin air and going to zero.
