Remember that it can protect you from  localized collapse, but probably won't help against a large one. Let's say you live in a small EU country like Lithuania and your country gets threatened by Belarus, or Russia, to the point that your citizens flee and economy collapses. Of course bitcoin will protect you. That said, if the whole EU central bank goes down, you'll face chaos not seen since the last World War and bitcoin won't help you much when there's nobody willing to trade you for it because people are busy barricading in their homes
