So the underlying question is "what unit should we switch to now", correct?
I'm a Bit hater for a few reasons...
[...]
If we drop "Coin" for less syllables, "centibit" or "millibit" are much better candidates.
"I just bought 100 millibits for 40 bucks!" ... "I just bought 100,000 bits for 40 bucks!" is a little excessive.
"
hundred milli bits"
Five syllables.
"
hundred thousand bits"
Five syllables.
"
ten million sats"
Four syllables.

Even better yet: I bought
10 mil sats - 3 syllables
Like it's been said, people don't like fractions, and are impressed with large numbers, this incorporates both.
