Hello, i have free electricity at my house. is there a site i can go to that will tell me which coins with low difficulty i can mine using my home pc's CPU? thanks.
Yes, you can try and use the nicehash profitability calculator.
https://www.nicehash.com/profitability-calculator/Do note that i wouldn't recommend mining on nicehash, due to their high payout limits and their sloppy security, (they got "hacked" recently.)
