What could go wrong with all cash?
One word; inflation.
If I could I’d do some metals; however all my assets are in a 401k which does not have that option....
401k, I am still a long-term retirement investor, where I think my dividends are re-invested tax free, and its one way to beat inflation. One family of funds had a mining company option, and from one thing I learned, own the thing that owns the thing.
