Bitcoin’s utility as a unit of account **today** depends on what you already believe about Bitcoin.

There is **no objective unit of value** that is measured with a unit of account.

It is all a matter of perspective, and relative value - how valuable is **this unit** relative to the unit of account.

Someone still lost in the dollar world looks at Bitcoin and sees wild and extreme volatility, whereas someone in Bitcoin looking back at the dollar sees a crash and subsequent bleed/stagnation.
