In fact, it doesn't matter how we call the unit that defines 100 satoshis. My point is that it's this basic unit that should be used.
Then go out and use it! If enough people agree to use bits, then that's what will be used. As it stands, almost no one uses bits. I much prefer using either BTC or sats, and not complicating things with additional in between units. It's fine to use sats up to 100,000 sats, and then use BTC from 0.001 BTC.
Talking in satoshis is the equivalent of talking in cents: big numbers for nothing.
So is bits. 1 bit is 3 cents. If you want an "everyday" unit, then the logical choice is mBTC, which is ~$30.
