well, this very interesting. Net hashrate is 14.6 gh/s. block diff is 800k - 840k (some times 900k). I have 12gtx1060 (1 card is out ATM). and 1 gtx 1070. I can mine on pool ~2350 - 2550 coins. I try to solo mine with old and new wallet`s. but for 24hours I not found any blocks! by current diff need to have 20 - 25 1080ti or more for profitable solo mining. but pool mining more profitable, anyway!
coin have dump by all exchanges, btc38 include. if we compare sigt and xcn, I go mine sigt ($25 from sigt vs $15 from xcn). so, where is "very profitable"? I realy don`t understand, sometimes I read post`s from some coins about very profitable solo  mining, I go to try, but no blocks. why peoples say about it? only new coin can have big profit from solo mine, but only few time. xcn is old coin, big net hr, big diff. where is big profit from solo?

I've contacted to Novaexchange about my lost XCN, they do not see any transactions to the wallet, but Suprnova shows coins were transfered.
What should I do in this case?
