Or the way people rush off to the supermarket and buy trolley loads of sugar when there's a powercut.
I don't share your derogatory opinion about people who stockpile food and items for personal security to be prepared for failures of the supply chain. Portraying these people as "tinfoil hats" tells a lot about you and your level of knowledge. Today's supply chains are far less robust than 50 years ago, because supermarkets have reduced storage space out of cost optimizations. A lot of products is delivered just in time. In addition, modern agriculture is resting on the shoulders of very few people and is highly dependent on specialized plants, fertilizers, pesticides and modern machinery.
Apparently you don't follow the news, because in fact the German government recently issued an official recommendation to its citizen to stockpile supplies in case of emergency. If you need an example why stockpiling makes sense, you can have a look at Venezuela.
What's disturbing is not that banks prepare for disaster. It's disturbing that they do it via buying Bitcoin, not by strengthening their system security.
ya.ya.yo!
