The first Bitcoin transaction using the moon was conducted in April when Brazilian researchers sent morse code radio signals to deflect off the moon down to Earth, and completed a Bitcoin transaction.

Imagine that you are without an Internet connection, in an isolated region and without communication. A small HT radio, a cell phone, or notebook with a bitcoin wallet, and a few meters of copper wire to mount a dipole antenna is what you will need to trade your coins freely, across the planet.

But, what if the other person who is going to receive it has no knowledge of radio amateurism and electronics?

How will they receive that signal? How will it replicate on the Bitcoin network? This transaction that now flies through space at the speed of light will use radio amateur radio satellites to listen to these sent transactions and replicate them on the network.
