May I remind you of something called "HALVING" before going crazy on a purchasing spree?
July 2016 is 10 months or 300 days away. Making this the perfect time to expand. Since you should roi in 250 days with this gear.
So basically you are saying that this invested money to risk getting any actual profits only during the last 50 days before halving slays miners in half (not to mention the previous increased difficulty from those who jump in)? hmmm....Not sure if I'd call that 'perfect.'
