a Whole coin is just an arbitrary concept. Owning one bitcoin seems like a big deal to us because we've seen it go from 0 to 69k. One "bitcoin" is just x amount of sats. One day owning .10 of a bitcoin might seem to the next generation the way we feel about one bitcoin now.

It's not like dollars, where 1 dollar was once what we think of as 100 dollars now. It's deflation.
