Your core premise is, again, flawed. You want a good way of storing ‘value’–which is a nebulous concept to start with–and then condition that premise on not using a fiat currency. Fiat currency is the best way of storing that value, and using that value at some point in the future. You could invest in stocks, bonds, money market accounts, or real estate, but that’s all still based on a fiat currency of some kine.
