Fiat is no value store at all, but gold is the world's best value store event, when compared to bitcoin. Gold loses its value from time to time but that's very rare and manipulative, normally gold is scarce and there's not enough gold in the world to spend at the rate that we keep spending, people think gold is only used to store wealth and sometimes accessories, but there's stuff in technology that uses gold as well, hell there's gold in every computer even if it's super tiny.
