I would like to know how many people all over the world owns at least .00000001 (1 Satoshi), and how many are in countries of latinamerica.
You can approximate how many people have one satoshi since there are only 10 mils addresses with 1 satoshi in balance.
My guess would be 1 mil.
About the location , nothing you can do.
Out of curiosity, how do you know there are 10 million addresses with a balance of 1 satoshi?
