Funny that's what they said about the S7. People STILL mine with them. If your source is right, add in the 24% tarriff and the shipping cost and your S15 costs $1500.00 to your door. At .055 per kwh it make $7.81 a day or takes 6.5 months to pay itself off. I'm no math whiz but for $1500 I can get around 7-8 S9i's these days that make $1.64 at that rate. My guess is that the S9's on ASICBoost will do just fine as long as your power rate is decent.

you do release the world is much bigger than the U.S right? i pay less than 2 cents per kwh , and 0 tax on asics. so my profit and ROI are pretty much different from yours , nobody pays 24% for miners except in the states " non that i am aware of". huge farms in china ship their miners in trucks " next door to bitmain warehouse" it costs them NOTHING to ship and pay no tarrif + they get good discounts on bulk orders !! and they get cheaper power rate than yours.

and ya people still run S7 but can you with 5.5 cents ? not likely !

what i am trying to tell you is (every one has his own inputs of doing the math), it may work for some while not work for others !

I will not buy any of those asics nor any other asics even with the dirt cheap kwh i have. but it's a matter of couple weeks till you see thousands of them being shipped across the globe mostly to noobs that will never ROI

I think he is off. If the Watt draw was that low, why did Bitmain release a 1800 watt PSU? My guess is 32 Th/s pulling 1600 watts ATW.

i do think he may be off in hashrate aspect, but as for power cons i think you are off, i am guessing 1400 or less , you know bitmain needs to target people who have only 100-140 volts too. and i do not think bitmain has any sort of psu that can supply anything above 1500w for those people. and ofcourse they would want to sell their psus as well !.

but still we are all just speculating here, the real numbers will be there in 2 days.
