My S7 Batch 8 makes me a bit over 0.018 a day on average, and in about 2-3 days, we are going get a cut of about 20% from today's earnings, so it will be about 0.016 a day from Feb 7th. After that, it will take another 8-9 days before we get another cut of 10-20%, this will continue until July 2016. After the halving in July, hash rate should stabilize. Maybe.
The next few difficulty changes could literally make or break profitability. If 20 continues I don't see price jumping that much each difficulty period. We honestly cannot guess what next one will be. Just not enough good info.
All we do know is China has some holiday coming up. So maybe they are pushing hard now, and it lowers (my hope). Or they keep pace of making this much hash till having (my fear).
