I've been mining at
http://qcn.cryptity.com/ since yesterday and paid less then 1/10 what I expect based on hashrate and blocks discovered.
Same here - Still they got msg in the header "On June 17th some payments failed! Working on a solution. Thanks for your patience."
My coins eventually turned up, I think the "June 17th" event recurred, without mention. But I think the operator is honest.
cryptity not working more time please move to pool dev active.
