Great question . I am using genesis alone at the moment for mining and really the concern over the last few months was the price of ethereum anx dash. These 2 beeing the main coins I mine with them.
Videos from their mining facility encouraged me and my belief has risen in them.
However I am not a big fan of the 2 years limitations of the contracts, so I just bought an ethereum mining rig for myself and I am looking forward to build these 2 mining facilities to a point where I can mine for myself and maybe rent mining power to others as genesis does.
Maybe this answers your question in a different way than you wanted, what do you think about my strategy ? Is it something you can relate to or improve upon ?
Just in case you decide to invest with genesis, use my referral and get a 3% reduction: mXLiHY .
