If the global economic collapse, even gold will worth nothing, don't mention the bitcoin. only food and clean water worth the food and clean water.
This is only true for the first few months/years of the crisis.
After that, when monetary economy begins to kick in again, Bitcoin will become one of the most valuable things out there.
Of course only if internet will keep existing. Bitcoin doesn't exist without the internet. So if a war / or heavy crisis happens and communication networks get destroyed/disconnected, we need to reboot Internet first before Bitcoin can prevail.
