Does mining actually can be profitable in 2016 guys?
As stated before, it comes down to how many time you want to invest and how expensive your power is.I started of by buying a kw/h measuring gadget and i let my SP20E run for a month, after that i calculated if i made any profit at all.
In my case i came out even, because the electricity is around 17 cents per KW. Still i find the exchange from money to electricity to BTC to money again quite fun and i like to fumble around electronics. So that's a huge plus for me.
And if you are here for profit, having a S7 Antminer would be a huge bonus.
I hope that's an ok answer for you!
