I'm sorry I corrected my post.
It was a mistake while converting my currency to usd.
It's 2.5cents per kwh

That's more like it
For an S9:
https://www.coinwarz.com/mining/bitcoin/calculator?h=13.50&p=1350.00&pc=0.03&pf=0.00&d=20823531150112.00000000&r=6.25000000&er=1&btcer=34366.17000000&ha=TH&hc=2407.00&hs=0&hq=1
So, basically $1.8/day net profit... Take the price you'd pay for the S9 + PSU + S&H + import duty + ... and divide the sum by $1.8. You'll see the the amount of time (in days) you'd have to mine to recuperate your hardware investment. If you trust the diff to remain stable, the price not to drop and it's before the block reward halves, you might have a shot at making money...
Some people also include the resell value of their hardware in this calculation... But be carefull: these ASIC's tend to break after a while... You don't have any guarantee you'll have something to resell in 6 months...
Actually we did the calculations, and since rental is not a problem since my partner is the owner of the place.
And we are accepting the fact that bitcoin might dip in the near future. And we found out that our investment can have a 3 to 4 months roi. Since when btc dips usually the difficulty will drop. And we are planning for a long term holding btc.
So my question now is which is the better option of hardware that is reliable enough with less maintenance and problems.
