Price and value are not the same thing, but when it comes to storing value, the price has to be somewhat stable aswell.
How do we express or measure price? (or value, for that matter)
What is the price of 1 USD, for example?
That is actually quite a tricky question. I think the price of USD could be measured by comparing it to what you can get with it. So I'd say the purchasing power measures the price. Currencies have no value intrinsically so they should be compared to real assets instead of other currencies.
Like I said, tricky question, but that's how I see it
