You would be far better off to stay SMALL and quiet. and private..under the radar and serve/help only yourself.
The cheap electricity is only blood in the water that attracts big bad hungry remorseless sharks
if you do 10 s-9's at 3 cent power you clear 20 dollars a day
10 s9's with psu's are about 475 each if you have a coupon
so 4750 / 20 = 237 days to break even.
not much to lose only 4750 plus setup cost for 10 miners.
so
100 miners means
47500 / 200 = 237 days to break even but you now have enough gear to be robbed
700 miners means 1 mega watt
1400 a day and same 237 days to break even. But you are truly worth robbing and a nice target to shoot at.
If you feel lucky go for it.
