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’re planning to leave with enough time, register a business or trust or something, transfer your money to a shell company, repeat as necessary then transfer it to the place you’re trying to go.
Use the tools of the people with money not the tools of people who get patted down for loose change by the tsa.
Has this worked before?
It’s one technique used to hide and move money all the time.
A different way is to buy some asset in the destination nation then sell it when you arrive. So like a bond or an etf share or something.
Extremely effective, happens all the time with amounts more than an average person can ever earn.
