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?
Same as with everything else: you sell them to someone willing to buy
There are random bitcoin/crypto ATMs in some major cities.
So probably there. Dunno if they require an account.
If you aren’t trying to hide the money, just find an online exchange like Coinbase or Kraken (they’ll ask your real identity of course), then link to bank account, and voila!
Also there are bitcoin ATMs everywhere. They’ll also ask for your identity these days.
