So, I have put together a basic PC just for CPU mining. I joined a DogeCoin pool and left my PC mining all night which was about 9-10 hours and made only around 1.5 DogeCoin. I can't even extract the coins until I have made 500. This really doesn't seem viable, unless there are new coins with lower difficulties I can mine?
For doge, cpu-mining is very inefficient.
You should go for some CPU-coin for your CPU.
