During a banking crisis, cash is a very good thing to have.
By cash, I don't mean bank deposits, T-Blls, brokerage accounts. I mean actual cash.
How to keep cash safely?
Lots of different ways, but if you keep it at home, have TWO safes: one that is very obviously a safe and easy to find and one that is very well hidden and fireproof. The real money goes in the hidden one.
Thieves and home invaders will be happy with the obvious safe and 999 out of 1000 of them will not even think about looking for the second one.
