Sure, I guess that there's not much difference in using three or four letters.. Pounds & Pence, Dollars & Cents, Bitcoin & Sats

Interesting point. Writings out sats or satoshis is not that difficult and is distinguishable.

I guess, similar to the redenominations of fiscal currencies over the years, the issue is then, for wallets to choose to adopt accounting in ₿ OR sats and [ satoshi ] would be transcribed into [ サト ] [ 中本聪 ] [ساتوشي ] [ Сато́си ] etc.

Maybe the simplest answer wins.

Or we just have fun with it and go for "₿s"

Not sure about that!
