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.
I am pretty sure that if there's a will, there's a way. Yeah people who are using bitcoin will find a way to transact with each other. Maybe a face to face trading using a Bluetooth or a hotspot to transact. Maybe using codes like what we used in out phone. Maybe through mobile phones then send each other to trade bitcoin or to transact bitcoin with each other. Maybe a peer to peer connection to exchange bitcoin. There is a lots of possible way if you really like to transact. We are now in the digital age and never let your mind to be occupied by limited resources.
