I really don't understand why people still buy this or GPU's to mine ETH, they don't do math?
ETH profitably was long gone...
Regarding this miner, even if it arrives NOW, would take about 7-8 Months to ROI ( with free power), in 3 months it would take what, 1 year and an half, 2 years? Totally insane.
Come on guys, do math, it's so simple!
When you say free power and 7 months, it looks good, don't ever say free power cause if you pay for power at $0.1, your 7 months roi becomes 30 months. Also difficult right now is something, difficult on july will be 2x what is right now, maybe more.
