Yeah there are precious metals demand deposit vaults that do exactly that. The cost to have that fully insured and also audited to make sure your exact serial numbers are actually stored and not secretly being loaned, etc, it works out to roughly ~0.4%/yr cost to store money in a bank like that. Which compared to ~0% interest rates in a saving account isn't that bad I guess.
Cool ... I guess you could vlog about the precious metals and get 1%/yr from Youtube to make up for it ... Keep saying "my precious" and you'll probably get a few million followers on Tiktok
