The 1070s and 1060s are still hard at it at ETH... every DAG is a mountain to climb now.
Sad to say that you need at least 1GHs now to make ETH worth to mine.... anything less than that will be just to tough.
Could you explain ?
I noticed for ethpool it requires a large hashrate to work properly nowadays. Is that what you mean ?
But for others pools like dwarf and ethermin , I think there is no minimum hashrate ? you can split hashrate to differents pools or differentsaddresses ? no ?
the diff level has gone in timebomb/ice-age mode, every epoch towards 150 will exponentially increased -- this design was put in place getting ready for POS and forcing miners to drop off POW.... but since they are not ready to POS.... this has created very long delays.... go and do a transaction in ETH and you will see the very long confirmation time.... looks like ETH team need to figure something out quick because there are many many new ICOs launching now
