It seems like #ecash is the ideal way to leave an offline bitcoin tip. Already I can print out the token QR and hand it to someone. Ideally, there would be a way to convert the #cashu token ID to something easily readable and writable like a short string of words. I could then mint ecash, print the words on small cards and then pass them out at restaurants, cafes, etc. The tip could even be simply written on the bottom of the bill. I have no technical understanding of how the token ID is derived, so no idea if this is possible. Just putting it out there. @calle
