I hope that it is not off topic but I am wondering if anyone else is thinking to get an Antminer Z9 mini from the second batch. I know that it is risky and chances to ROI might be very low but it costs now $850-250 (coupon) = $600 and the chances of Zcash forking this year are low. I like the miner: low power usage, low noise, small. In the worst case scenario, I will have $600 paper weight (or I will lose the prepayment). What do you think? I cannot imagine running S11 or anything else requiring > 1200 W with the noise level > 76 dB at home (I will actually need another upgrade to my fuse panel and I am risking the wrath of my wife  ). What do you think? I was contemplating getting FPGAs from Senseless or Mineority but it is a lot of money and unknowns. In my mind, GPU mining is dead (I am mining practically only Ether now)
