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 what happens to Bitcoin if internet goes down?
home internet and mobile internet goes down
do not mean trade bitcoin to buy/sell i mean using it as a way of payment say you wanted to send money to someone abroad for family far away
If no internet, no wifi , bitcoin or blockhain won't work. Because bitcoion cyrptocurrency is attached to internet world. Then we will go back to using fiat. But this scenario is very unlikely to happen.
