Would Bitcoin survive through offline solutions like mesh networks and satellites, or would it completely halt?
Internet covers everything online and nothing can function without the internet. Everything will be shot down for a period of time but definitely resume back when the internet arrives, and be careful not to be panic, because it causes heart aches who can't restore itself back.
You could remember when Facebook shot down few years ago but Facebook lost millions of dollars within the the short period of time, that's the power internet has, value it.
