Can I use my PC to mine other cryptocurrencies that use Scrypt or CPU and GPU mining are long gone?
I've also found the PACMiC V3 which looks like a good option!
You need research first when you want to mining altcoin, mostly altcoin is easy to dump and pump, find a promising altcoin and also research the difficult too, see this link:
