I don't even think this should be a debate. Every ISO currency makes use of 2 decimal places.
This is simply wrong:
https://en.wikipedia.org/wiki/ISO_4217There are
hundreds of
millions of people who use currency which is not subdivided into hundredths. Why would they want to adopt two decimal places, just because bitcoin?
An international standard needs to treat all peoples equally. I think we should choose the lowest common denominator (i.e. the smallest possible denominational unit) as a compromise between the diverse financial traditions.
