Haha a distributed network spread across a hostel could work well. Especially since these mining rigs can be used as fully functional computers, even play games while they mine. I had also explored renting out these systems to startups for negligible fee with the condition that they would need to insure 24/7 power and internet, but it needed too much initial investment for me to get into.
I do know a few people in Bangalore itself that pay a fixed amount for electricity, and for such arrangements mining rigs are pretty lucrative.
Don't say this can happen only in India though, most of the worlds renewable electricity supply is dirt cheap, like hydel power plants etc. Toonim brothers, who operate a large mining facility, are located next to a Dam/Reservoir and have dirt cheap electricity. Most of the Chinese operations rely on dirt cheap/free electricity, and over 70% of the worlds hashing power is located there.

Anyways, I'm still bullish on Etherium, but a little unsure of Zcash. I'll be mining and holding for a while, im in for the long haul. Remember those stories of people who had mined a 1000 Bitcoins and held them, then the price broke $1000? A million dollars from a few PC's running unattended. That's the dream.

Free electricity ,where?this is the first time i heard free electricity supply unless someone stealing it.can you tell me place in daman where this free supply is available.
