Hello, I'm thinking on taking some Antminer S7 and start mining but I'm wondering if it'll be profitable with a $0,032/kWh electricity ?

http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=4860&p=1210&pc=0,032&pf=0.00&d=317688400354.03400000&r=12.50000000&er=900.57000000&hc=0.00

Long story short, at current diff, price and block reward, you'd make about 100 bucks a month.

Now, you can see which risk you're willing to take... see how much an S7 + PSU + air conditioning + shelves + tax + shipping would cost you, divide it by 100 and see how long it'll take you to break even.
Do realise the price is dropping, the diff might rise, the block reward will halve in a couple of years,... I'd personally guesstimate i'd make $70/month instead of $100 to incorporate the risks, and i'd personally want to break even in less than 6 months... So, personally , i would only undertake this endaveour if my total purchase and setup costs were lower than ~ 6 * 70 = $420... but then again, i'm not really a risktaker Wink

Thank you for your answer,
$420 for all the setup is just impossible in my case Sad

just the shipping price will cost me like $100...
But why would you want to break in less than 6 months? I have read that the Antiminer S7 have 5 years lifetime, is this true or just bullshit? also I wanted to know what is the importance of the batch number when buying a miner.

because otherwise you are taking a gamble against the diff, that always increase especially in a bull trend like this

there is big margin in profit for miners now, so don't expect that they will not add more hash, it's always better to roi fast

if your electricity isn't a problem like it look, you can try a s5 also, far cheaper is second hand
