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?
Wow butthurt much? Silicon valley is the world center of IT innovations, whether you agree with that or not.
Also, Dollar is 2 syllables. I've never been to USA, but I do not think that in shop you can often hear: "This will be 2 US Dollars" unless you live at the Canada border.
No butthurt (whatever that means.) But there is a vast amount of innovation outside of Silicon valley. I never said US innovation isn't important, it is just by far from the whole story. For the record the Silicon valley accounts only for a small part of US innovation. It is far from being the center of innovation in the US.
As for "Dollar", that by itself doesn't mean USD, or US Dollar unless you happen to be in the US, then the term dollars is used by itself. Dollar is used for many world currencies.
http://en.wikipedia.org/wiki/Dollar The confusion isn't just for those living at the Canadian border. I have traveled a lot, and term dollar is ambiguous. Bitcoin is clear though, unless you are taking about both the network and BTC.
For the record I actually happen to be a US citizen and I work in the high tech world. I currently live in Japan. In many ways the US is very backwards and even primitive. For example broadband in the states is overpriced, slow and often hard to get.
