I'm a firm believer in tangibles. Gotta keep it tangible!
Crypto is not tangible. Never trusted it. Plus, as far as I can tell, if the power goes off or the Internet gets shut down, you can't access your crypto. And no major companies can accept it then either.
Dollars used to be "solid". But it's losing credibility fast. Inflation is destroying it. Gold is solid but who's gonna carry around a bar of gold? And how do you buy a loaf of bread or some other small purchase with it? Pull out the Swiss Army Knife and scrape off a sliver? And how many companies will accept it? Plus the government could do as FDR did and make the private ownership of gold illegal. Too many variables.
Silver is better IMHO. Old US coins (pre 1963) used to be 90% silver. Can be used a s face value currency or silver weight in barter. Plus there's more of it in nature than gold.
Land is also good but can be confiscated.
Barter is what I expect to come out on top in the inflations wars. If you have goods or a skill that people want, you trade for what they have that you want. Very good incentive to get trained in a useful trade. I have skills, and I'm investing in barter tangibles (tools in general, anything Snap-On, flashlights, seeds, fertilizer, booze, coffee, ect).
Though I've just heard about Goldbacks. "Paper" money with gold impregnated into the fabric that it's weight equals the value of the currency. As small as about $4. All the positives of physical gold with the ease of currency. Plus if worst comes to worst, you can dissolve the bills in a strong solvent to melt the polymer coating and extract the real gold. Might be worth a look-see.
