Hi, newbie here. I'm trying to mine ChainCoin, but I only found the sgminer and it seems it doesn't like my 3 x 1070 GTX and crap out an error when I tried mining ChainCoin with it. I see that you seem to say to use ccminer?
Yeah, make sure to update your NVidia drivers to the latest version and remove all overlcocking. Get ccminer alexis78 and get it up and running. Once its running, only increase the core clock in steps of +10 until it gets unstable.
I took that version. Is this good? I'm using it now on the pool. also, I got hashrate of 36MH/s per card (I suppose?) I have 3 x GTX 1070.
http://github.com/KlausT/ccminer/releasesI see that the accepted shares are at 99.55% on every share, but when I started, it was at 100%, is this good too?
Also, big newbie question, I use to mine only using the NiceHashMiner that was paying every day in BTC and I could then withdraw from the NH wallet. Now, I created a CHC Wallet using the wallet I downloaded from the chaincoin.org web site. It's my first time mining in a pool, so how does it work for the payout? I suppose at some point my payout are sent to my CHC wallet ? (what are the fees?). If I want to exchange my CHC for some BTC later on, or just sell them for USD$, I need proceed how?

So much newb quesitons. i just want to payback my rig first as fast as I can (I took a small loan and still have 2k$ to payback on it).
The ccminer version I'd suggest is ccminer-alexis. You're total hashrate is probably around 40 MH/s with 13 MH/s per card. 100% acceptance rate over several hours of mining is quite hard. Sometimes your internet is lagging, or your GPUs need longer to calculate a share and then your result gets rejected. It's normal to not have a 100% acceptance rate, as long as the reject shares rate stays below 10%.
Most of the pools (including this one) pays out in the currency you are mining. Thats why you have to provide a CHC address on signup, so your shares of the block reward can be send there. As the post states the fees are only 0.25% and everything else goes to the miners. Indeed you can exchange your CHC coins to BTC and even USD using an exchange. Google 'Novaexchange' and 'Cryptopia', those are the ones trading with Chaincoin.
Getting ROI (return of investment) for your rig with CHC is currently very possible
