-I have access to free electricity and a couple dozen Windows pc units. I'll post the specs at the end.
-What I want to know is, what is the easiest or most profitable cryptocurrency to mine?
-I do not have any money to buy any extra equipment or do any upgrades.
-Please point me to a guide on how to mine whatever you suggest.
SPECS.
CPU: i3-3110M 2.40GHz
Ram: 4GB
GPU:
https://ribletjorb.tumblr.com/image/163358130871You have onboard GPU, mining will burn the board.
you can mine with cpu though, but it is very difficult to see any significant returns.
what you can do is, go to minergate.com
download gui and run the miner. Select altcoins and note the hashrate. Now multiply with pc units you have. That is your total hash. Goto the minergate calculator on site and see how much you can make with this hashrate.
Good luck
Yes it is on board GPU. you will not get access to mine GPU you must use CPU mining. i personally had experience in CPU mining this is not worth to mine. yes, the returns are very less, and you will lose your system very quickly. Don't think only about free electricity think about your what system you are going to use. For CPU mining I think you don't need more electricity. You can invest some money and setup GPU mining then this free power will help you to earn 10 to 15% profit.
