I have a feeling that Solaris will be unprofitable for mining in the next coming weeks maybe even days. For those just joining the thread :

3x GTX 1070:
 - I started mining 10 October on nvOC
 - 2.8 - 3.2 Mh/s per card = 8.5 - 9.6 Mh/s
 - I was getting 9 - 10.5 XLR per day
 - Today I am getting 6.5 - 7 XLR per day

Based on that in 9 days the difficulty went up in such a significant way that I will mine 30-35% less than a week ago. Currently it is still profitable and if the price shows us promise it might still be for a while.

Just my observation since I started mining
