That's what Unit of Account is. The one that's so popular all goods are priced in it.

Here in Australia, publications always use AUD. In Britain its the pound. BTC or gold would be my choice. Maybe XMR if the context is DNMs.

Can you show me some prices you're quoting in BTC or gold or XMR.

I'd be happy to see other units of account in niche circles. Hey maybe I'll participate in said niche circles even. They just might catch on. But there aren't any.
