given the cayos happening in the world i wouldn't be surprised of nuclear war and in this case i would expect internet disruption question is how do we trade bitcoin during this time if we can't access internet.
home internet and mobile internet goes down
Bitcoin network completely breaks down. no hash power, no node. no confirmation, then we have to go cash, like dollar, euro.
You forgot gold, silver, juwelery, whatever that has some value. Maybe you can sell your body if you have no paper money or value things. Be prepared for it should i say. We definatly gonna get crisis at the world.
