Since #Nostr is crackling with high voltage monetary energy in the form of Zaps!⚡️ why not adopt the ⚡️ emoji for satoshis; similar to how bucks are for dollars.
21 zaps = 21⚡️ = 21 sats
And while we’re at it, to avoid confusion between lightning/email addresses, ‘simply’ swop the “@“ for “⚡️”.
i.e. bitcoin3us@getalby.com becomes bitcoin3us⚡️getalby.com
