Frens, need assistance!

I’m publishing a book this month, and trying to get the wording right on my editioning page.

I will be reserving 21 copies to be sold for Bitcoin, approximately 1,000,000 sats.

Want to be clearer about it in my copy.

“21 sovereign copies editioned by block height”

That’s what I have now but not many people will understand that.

Any ideas?
