I have an interesting point to Yacoin's popular criticism. People have accepted Peercoin as valid distribution and stable store of value. I agree with those people.
http://peercoinmyths.com/Myth 3 - Peercoin (PPC) was insta-mined.
Fact: Some people like to point out the high mintage in the first few days of the launch, this is another misunderstanding. In the first few days of any publicly released cryptocurrency the mintage is going to be relatively high because difficulty is low and lots of miners would like to participate, causing blocks to be generated much faster than usual and resulting in high mintage per day. Unlike most other altcoins, we already tried to mitigate this by starting difficulty at higher initial value of 256 and also further reducing the number of low difficulty blocks via continuous difficulty adjustment.

Basicly Yacoin was as fair or fairer than Peercoin. I guess we should compare various "richlists" to see if the situation has leveled since then.
