I believe the words you are looking for are “witness” and “partner” - I kept wanting to insert them in the piece. Nicely related though, Tomer - appreciate your work as usual!
For your reading pleasure, I present:

I went with companion, but I do love “Witness”. Reminds me of Stranger In a Strange Land
Exactly my thought - Bitcoin is a dispassionate observer and witness to our activities - I equate companion with some emotional attachment or support. I’m available as an editor/muse ✍️ anytime brother!
