Why is Bitcoin becoming the most widely desired commodity? What is the utility of Bitcoin according to the Regression Theorem? Precious metals have ornamental utility for displaying status conveniently. The rest of the commodities have obvious utilities. Bitcoin is just a ledger. What is Bitcoin's intrinsic utility?

I'm not saying Bitcoin has to have one. But the point here is that you invoked the Regression Theorem and I would like to understand why it works for Bitcoin.
