How do I do the maths for starting a bitcoin mining startup in Kuwait?
There are many bitcoin mining profitability calculators all over the web:

You would have to get your hands on some hardware, which can be quite expensive indeed. The only advantage you have is the recurring electricity cost, but note that the hardware is not cheap and often takes many months to make profitable. You'll need a good contact at BitMain or some other ASIC manufacturer so you can get your hands on the latest hardware early so you can mine them for the longest time.

Best of luck!
