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?
Consider the worst comes to worst, you won’t have electricity, let alone internet connectivity. Good luck selling any crypto in those circumstances.
Nope, ye olde Gold & Silver are the way to go. Silver for fractional trades, gold for larger ones. Can’t beat a couple thousand years of history.
