I'm not an economist, but I still think that the "value" of something is what people are willing to pay for it at the moment. Please correct me if I'm wrong.
You could resell a loaf of bread if you want and maybe make a profit. You could also eat your loaf of bread if you do not want to re-sell it.
What would you do with your bitcoin if you could never sell it

NOTHING That means it has zero intrinsic value. The only value that Bitcoin has is what some greater fool will pay for it.
And still your loaf of bread is terrible money and will get bad if you don’t use it in some productive way. That’s why it’s not used as money.
While Bitcoin is just amazing at being money, and that’s enough for being just money. How many times did you use fiat for other things than money? You can’t eat, drink or do anything with it. And yet still want it more than a loaf of bread, that’s the irony. You don’t even understand money and would still prefer it over an actual economic resource. Because you understand that money can acquire you any economic resource you want, and that’s the purpose of money. Enabling universal indirect trade.
There’s a difference between an economic resource and money. Money is non-productive by nature, while economic resources are. This means money is used to acquire, trade economic resources and make production happen, but not used to produce something directly. While economic resources are used in the opposite way. The good that can fulfill the function of money best, will become the dominant money, it’s that simple. It doesn’t matter if it’s usable in different ways itself or not, for its success as money.
