The fact that the Indian Rupee's exchange rate against the dollar goes up or down is not something I care about at all. Because I measure the value of ₹1 based on personal yardsticks that I have in my mind sub-consciously.

The price of Bitcoin, as determined by speculators and market makers, can't inform me about its market value reliably.

If there are real-time market prices for goods and services priced in Bitcoin, then I can accurately measure if Bitcoin is a good store of value.
