This avoids having to move the decimal again too soon, and just adds consistency to the entire scheme (move 4 decimals each time, add 4 decimals any time we need to subdivide further.)
Plus, I again would suggest that many of us who are tech-minded seriously underestimate how much the average person (ok, maybe just the average American) struggles with the idea of a milliBitcoin or microBitcoin. It's just not user-friendly. Saying "a digibit (nakamoto, myriabit, etc.) is one ten-thousanth of a bitcoin" or "there are ten thousand digibits in a bitcoin, ten thousand satoshis in a digibit" would actually allow the convention to spread quickly and to stick.
All it would take is a decent name for the unit. Suggestions?
Suppose everyone jumped on the bandwagon for using 0.0001 and whatever cute name is proposed... No one has any idea where the value of Bitcoin will end up if/when it becomes widely used and somewhat stable. So why pick an arbitrary (negative) power of 10 and hope it becomes the most convenient, when in all likelihood, you'll have picked an inconvenient unit?
It's not arbitrary. It's the halfway point on an 8-decimal-point scale. It reduces the movement to satoshis down to 2 equally-spaced steps (and the "cute name" war was lost when the community, for whatever reason, went with "satoshis" as the name for the smallest unit.)
Yep, yet it was a deliberate push by enough supporters that made "satoshi" stick, despite detractors (of which I was one.)
If it can be done once, it can be done again. I don't really care what the name is (actually, I do have my preferences,) so long as there is one for the unit.
Most "non-techies" I know would consider it anything but practical. Sorry, but there's no way I'd ever advocate for it.
