I tried two cinnamoncoin pools and both of them looks like SCAM.
My miner runs with one Gigabyte 7990 @ 1.4MH/s, I first tried
http://www.cinnimine.pw but after several hours the unconfirmed balance stay at 0 and pool's invalid percentage was huge (about 60 to 70%).
Then I tried
http://pool.800996.com:8502 and unconfirmed balance grows in minutes but after generating a deposit address on coins-e and configure automatic payout, I figured out that all coins I mined were lost: about 160 CIN were sent but my balance at coins-e is already at 0 about 20 hours after first deposit.
EDIT : the support form obviously didn't work.
I'm not able to find any other CIN pool, perhaps I should do solo mining on this coin ?
