I guess you didn't read the rest of the thread before replying to kokojie, since you missed the fact that kokojie's figure is off by an order of magnitude:
Some of them are zero, and by the author's own numbers:
There are 732,959 addresses with a 1 satoshi balance totaling 0.00732959 BTC
Most of these "unique addresses" are like that, with balance below 0.001 btc
So I guess I was inaccurate when saying "non-zero balance addresses", I should have said addresses with "meaningful" balance.
