I tell everyone to prepare for the day when their fiat currency buys nothing. That day is coming soon. Without any way to buy, will you eat, be warm, and be safe?

I would not depend on crypto either. The banks control fiat to crypto transactions. They can shut those down like China is doing now.

Get your supplies first. Get out of debt. Then get stuff you can barter. If you have all of that, get some precious metals.
