I personally think gold has industrial value, aesthetic appeal, and public consensus: gold = money. But if there’s really a world war and you need to flee, I feel gold is far less practical than virtual currencies, especially something like Bitcoin. Gold is pretty heavy and not easy to carry around. If you’re flying or taking a ship to a neutral country without war, you’ll definitely face security checks, and it’s super hard to bring along. Bitcoin, on the other hand, is much simpler and way more convenient. Only if the entire world loses internet and electricity, or if there’s no war but fiat currency is massively overprinted, then I think gold would be more reliable.
