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 ?

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
