Ether mining with Genesis is pointless in general.  For the price of 20 MH/s which is $880.  You could buy a half way decent PC, stick a 290x in it and get 27 MH/s and have full control over what your system is doing.  FYI a 290x only costs, after a discount on Newegg, $290.......  So yeah you could get almost Triple what Genesis gives you if you have a few random PC's sitting around that could handle a 290x tossed into it.

So Basically the pricing they have for Ethereum mining is a complete and total ripoff, especially if you consider within 10 months or so I believe I read somewhere Ethereum is switching over to PoS only.
