24/7 Selling Hashs

[Charmello]

So currently, I am going on a trip away for a month, and am wondering if I should leave my computer to sell hashing power on NiceHash. The Gpu I have is a gtx 1070 and is around 68C when mining. Is it okay to have my gpu running at that temperature for 1 whole month?

Heat won't be an issue, but power could (storms, outages, etc). Is this system connected to an UPS?

Also, do you expect to earn enough money to offset the electricity consumed?
