That is not bad at all. Equivalent to $2286 for a 1TH miner, except that you get the ability to overclock and stock clock for as long as that makes sense, then switch to low power for longevity. I like this a lot.
A good idea, and a better solution than an S2 for sure, the only downside being that it'll never make back the 3.5BTC it costs, but at least you'll lose less than the 7BTC an S2 costs
The entire mining end of coins will die by oct without a decent fiat price rise.
Basically power cost plus diff rise will kill it off at the price of 450 usd a coin.
Diff goes up too fast. power is in fiat.
an s-1 at 200gh 400 watts 18 cents a k-watt btc 450 does not out earn power cost at a diff of 22.
even a sp10 at 1th 700 watt mode does not out earn power cost at a diff of 70
at 20% diff will be 75 at sept 10
