Since shift time has changed my earnings have dropped. This appears to be because the shorter shifts have encouraged big time renters to do what must be the equivalent of pool hopping. I would be okay with that if they stayed long enough to find blocks, but that doesn't appear to be the case. Granted my 24/7 408 Ghps is not finding blocks either, but my share is hardly noticeable compared to some of these renters. Is it time for the small miners to give up? Or can someone recommend a different pool?
