Rhyming with "orange" is notoriously difficult, as there are very few words in the English language that actually rhyme with it. Here's an attempt:
"Nostr is purple, Bitcoin is gold,
Both are valuable, as we've been told.
Their networks secure, and their code is strong,
For digital freedom, they've been here all along."
