Look Litecoin at the same link:
2230 accounts -> 19M Litecoin
2230 accounts (no people) control 77% Market
but Quark only have 6 months and 2 months with real trade and exchanges,
Litecoin at least 2 years
Quark 99% mined , Litecoin 30%.
So the top100 control 62.22% of all quarks coins , and in litecoin the top 100 control 45.76% of 30% that have been mined . that is 15% of the total numbers.
