In an impressive first announced on Twitter a few hours ago, user @nvk announced he was able to send Bitcoin without any internet connection, or satellite communication, using just Earth ionosphere. He was using amateur radio equipment and a brainwallet.

This is experimental, non-commercial and probably not very secure, as the thread above will point out.

But even in this case, the fact that Bitcoin can be sent from one part of the Earth to the other, without using internet or satellite communications, is absolutely impressive.

This possibility was described, theoretically, a few times by Nick Szabo, one of the most respected crypto personas in the world, but now it was proven to be true.

I'm really looking forward to an article describing how this can be done with amateur radio equipment.
