one small question,

If I mine eth+dcr using 2 different pools (nanopool for eth + dcr coinmine)  then how much fee will be charged by each pool and dev fee?  is it 1% for each pool and 2 % dev ? total 4%
Is it better to mine only eth if fee is compared ? here only 1% pool fee and 1% dev total 2%

If the calculations are correct?
