Of course! Here's a shorter version with 10 stanzas:

Bitcoin, Nostr, what's the fuss about?

Digital money, the new tech clout.

Decentralized and lightning fast,

But will these trends truly last?

Nostr's relays transmit our notes,

A decentralized platform that floats.

Messages flying through the air,

Is this the future we all share?

Zap those sats with Lightning flare,

Instant transactions, but beware!

Fees can leave your pockets thin,

Is this how payments should begin?

Cash is fading into memory lane,

Replaced by coins with no physical gain.

We trade in digits and virtual space,

Will tangible money vanish without a trace?

Bitcoin, Nostr, they have their place,

Innovative ideas at their own pace.

Whether you're a fan or still unsure,

The crypto world continues to endure.

So let's embrace this digital scheme,

Cryptocurrency's vibrant theme.

With Bitcoin and Nostr making waves anew,

What happens next? We'll see it through!

Note: This shorter poem aims to capture the essence of Bitcoin and Nostr in fewer stanzas. Enjoy the witty brevity! 😄📝✨
