As long as we are talking value and not nominal price.
If we go into a deflationary spiral, the nominal price of everything declines. The value of the asset—how many widgets per dollar—will retain its value greater than any fiat based asset.
Hyperinflation is a no brainer.
Value is critical. Price is not.
That is why if one believes hyperinflation will happen it makes sense to get those long term purchases done before it happens. Car, appliances, new roof on the house, etc. The money's not collecting interest in the bank, and who totally trusts the banks with savings if things go crazy?
