Bitcoin’s utility as a unit of account **today** depends on what you already believe about Bitcoin.
If you are skeptical of Bitcoin, it makes no sense to use it as a unit of account.
If you believe that Bitcoin will become the world currency, it makes no sense to use anything else.
If you want to end up with as many bitcoins as possible, you should price any investments or ventures in Bitcoin.
That’s how you know if you are winning or losing against your benchmark.
