Most people in the
world do know milli (10
-3) and micro (10
-6). These are standard in SI units.
http://en.wikipedia.org/wiki/SI Now if you talking about USA, maybe you have a point, but the USA is has less than 4% of the world's population.
4% of population? Indeed. But in this industry two things count: money and innovations. In both of them USA are among the world leaders.
My two cents: are "bits" a good name? Nope.
Are SI prefixes a better way? Not at all. Bear in mind, that most of the world currencies use two syllables at most. mBTC is already 4 syllables. Way too many to be used outside of the internet.
I am also not a fan of satoshis - this is also too long. And too unfamiliar for western speakers. Already mentioned "nakas" would be better, or something similliar.
Well the US Dollar is 4 syllables and even the brief form USD is three. So much for that theory. In Japan the "yen" is pretty unique and only one syllable. I asked my 10 year old and she knew what milli and micro meant. Japanese education includes that at least.
For trading you can just use Bitcoin. The other forms are for shopping.
Oh and Japan is amongst the world leaders in money and innovations. In fact Europe is too. Although the US might be the undisputed king of McJobs that don't pay enough to live on. Maybe "Mc" should be a unit?
