I am running NIS on desktop and want to shut my desktop down each day. I want to harvest when the PC is switched off. I have enabled delegated harvesting. If I connect to a remote host in the settings and start delegated harvesting can I then close the NCC client and turn off the computer and still be harvesting blocks 24 hours a day?
Yes, that’s the point of it 
Good luck !
install NIC on a raspberry pi 3 or ASUS Tinker Board (4gb) and you can harvest the cheap way
