Obviously the store of value part pushes up price, but there is also a big need for gold in electronics and jewellery etc. Bitcoin at the moment is largely speculation and has little use beyond that currently, though has potential to become an active currency of significance, we are yet to see that.

USD is useful because it is a meaning unit of exchange.
If a marginal producer can generate a kilo of gold for $60k, then gold is worth around $60k/kilo. Its uses or lack thereof are not that important. If all the uses of gold went away magically, it'd be worth less for various reasons but still a similar order of magnitude.
