In addition to the existing Expanse Mining Pool (with 0% fee) we have established now a PPS (Pay Per Share) based Mining Pool: http://exppps.ethertrench.com/#/
The advantage for the miners is that each share is accounted and finally payed, independent from the luck of finding a block or an uncle. So steady income with no risk for miners.
As a matter of fact, the pool basically takes the risk of the variance, therefore we take a fee of 2%, but remember this covers bad luck and also lower rewards from uncles.
Would be great to welcome some miners on the PPS Expanse Pool!
