Maybe this is why I do own and operate a Data Center with my own mining rigs.
We pay 25 USD per Gridseed Blade and making per unit around $1 currently per day in profit after electric costs. Try to beat that.
One thing you have to learn is upfront Investment with ROI if you don't do this right you pay out of your own pocket.
Again, you're just trying to be right! My client's Zues miners hit ROI month$ ago! It'$ ALL PROFIT BABY! SORRY BUT YOU CANNOT BEAT THAT!
Oh, and there is no way that 5.2MHS will earn $1 per day! Don't be ridiculous! You mean more like 40c to 50c per day if that! And that is IF You can keep them from overheating TRYING to keep up with ANY ZEUS miner running at STOCK SPEED!
