I see that this concern about Bitcoin working "off-grid" is shared by me and many others—maybe it's a silly concern or just a newbie thing, I don't know. I've seen all kinds of projects, from transactions via audio code, satellite, to Reticulum, but thinking about it, if the internet somehow stops working in the current state of human society, Bitcoin will be the least of our problems. In specific situations like power outages or state restrictions, projects like these really shine, and I'm very curious to see what they propose.
