Looking at how fast coins are coming in for me that actually is a very good price. At the current price there i would make little under 0.05 btc per day. compared to 0.008 on the bigger coins.
Spent some hours for testing bitcore sp-mod 2. Get best speed for 1080 ti with -i 23.15 --gputhreads 2 up to 35 mh.
The --gputhreads parameter is not done yet (cpu validation errors), but you can start 2 instances of the miner to get a similar effect. Workin on a fix in #3.
