For the immediate situation in every collapse. And I mean every collapse, see Cyprus, Venezuela, Zimbabwe, etc. Cash is King! Gold and silver are for buying up assets on the cheap. Discount real estate, discount cars and trucks, lumber, farm land. All real assets. But in the immediate, cash. Always have cash.
In all recent collapses, crypto also would have saved people. In Cyprus, he who had Bitcoin, bought the land... It's new, it's not gold, but it would have worked like the bee's knees in Cyprus!
