Lol, I have seen all:

- Adopt the bits standard

- People will learn to count in decimsals eventually

- Adopt the 3 horizontal bars symbol

- sat with s in plural

- SAT never with s

- sats always sith s

- mirrored dollar sign $ for sat/SAT/sats (one of my favorite)

- now the ₿ is sat

This last one might be the most obvious for new users but quite confusing if not scary for existing ones without too much experience.

On the other side, people in finance are used to stocks being fractioned, so it might be ok if properly coordinated and informed (which is hard to achieve in a decentralized project like Bitcoin).
