I am suggesting a compromise where we say 10 n₿ instead of ₿1 when we mean 1 Sat. This way the recognisable B remains, and the metric micro/nano etc convention is not novel. We already had this in ancient apps like Electrum but in the form of mBTC for milli BTC, I am just saying make it n₿, cleaner. And we get rid of the annoying jokes about B1000 being too expensive, you can't make that joke when it is clearly 10000 n₿. Of course people will object to the concept of 1 n₿ like they object to milli sats, but it is safe to ignore that argument just like it is safe to ignore anyone who thinks sidechains are not valid scaling solution, in that you can just do it and let them tell you it is impossible all they want.

fwiw I actually tried "millibits" for a couple years, when I ran the Xotika platform. It was too confusing to have so many denominations. BIP 177 really is the solution, waiting for when Bitcoiners realize the "whole bitcoin" meme is useless. One BTC might never be $1M, so these arguments could also be premature. With modern tech, conversions could all happen as credit and denomination becomes less important.
