I started using Nicehash and have left my PC with the program running for about 12-24 hours at a time with no problems that I can tell. Im going on vacation for a week and I want to know if it is a bad/dangerous idea to leave my gaming PC(RX480,i5 6600) running 1 week 24/7 with nobody at my house to watch it. I only mine with the GPU not Cpu. Is this safe and does anybody recommend it?
