What kind of things could a person carry to sell and how if they ever had to forcibly leave?
I read diamonds are worthless second hand.
Solid gold seems legit but not sure if coins or jeweler is best.
I saw something about getting gold chains to trade individual links in a emergency.
Are there any other good tips?
Stupid question. How do you then get cash for that wherever you end up? Do you need a bank account?
There are random bitcoin/crypto ATMs in some major cities.
So probably there. Dunno if they require an account.
