Depends upon the electricity costs. Oil drilling wells are using the flare gas that usually gets burned off to produce electricity from a "free" energy source so just the cost to set up & operate the mining rigs. Here in FL our electricity costs ~.07/KWh so I'd be profitable at current rates.
My condo neighbors wouldn't appreciate holes in the side of the building to vent the heat. I'm VP of the board for our community so probably wouldn't be a good look.
The difficulty can go down as much as -75% every 2,016 blocks. I'm pretty sure it will be profitable quite soon, otherwise the network would cease to operate.
Mining is and has been on its way out since even before Ethereum's time. Anyone who invests in equities who's business model is to follow mining, is just wasting your $ into a dead-end tech.
I know of some people mining in Icelands and making alot it can definitely be profitable but got to find a good set up for sure
Nice.. 7 cents per kWH is excellent. I pay 9.5 cents on the Treasure Coast, the commercial rate is lower. An ideal place would be cheap power, decent broadband and a very cold climate lol.
