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?
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.
