Bitcoin-denominated Cashu tokens have been transmitted via sound, qr codes, stenography, rf radio, satellites in space, nfc cards, bluetooth, emojis, text messages, nostr posts, api calls, and even bank transaction memo fields.

The reason why this is happening is not only because it's extremely fun. It's also because Bitcoin is natively digital money. Bitcoin and the people using it are exploring all possibilities to transact between each other. This is the real digital energy.

Cashu makes Bitcoin light as a feather and transacting with it as easy as it can be. This is what it looks like when a new electronic money is starting to permeate our world. Bitcoin will be literally everywhere and in every corner of the world, just like the internet already is. This is what it looks like when that happens.
