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.
Well the thing is that cash is going to disappear in the next 10 or 20 years so I wouldn't count of cash as a means of exchanging value in the future because society is going more and more digital and physical payments will be irrelevant, the people being born today will not know cash in the future.
