I have a bitcoin paper wallet I want to use to buy XMR. Is this possible without any intermediate crypto?
I only see that I can add an "Altcoin account" which does NOT include bitcoin. Weird ??? I know Bisq comes with an internal bitcoin wallet or something. Do I need to transfer my BTC to this internal wallet?
Also, when I go to the Buy tab, the only "Payment method" listed from sellers is "Altcoins" or "Altcoins Instant", so paying with bitcoin is out of the question ?? Or what am I missing ??
Exactly, I'd still place bursts of radio signals (like that of a pulsar or morse code transmitter) under the umbrella term "radio communication". Just because it uses the radiation that is at the radio frequency. No matter what the format/arrangement/method, which includes encoding and using carrier waves.
Then you also have electric waves that travel through conductors, although this is only a part the electromagnetic wave used in the air. But you can change the frequency of this electric wave perhaps to the radio frequency. So perhaps there is also radio communication through wires
