Retailers don't accept Litecoin or Ether either, and very few accept Bitcoin.  No cryptocurrency will have its price based on its utility, ever.  Their price is only based on the money that people hold in them, and utility is part of the reason why people hold money in it but they don't just put it in, spend it and be done with it.  People also don't only hold money in PayPal that they're spending that second.

And yes, it's daily price changes.
