Its been a long time since I've visited this thread!
I recently switched energy provider to one that gives cheaper electric for 4 hours overnight between 0030 and 0430 so I can charge my Nissan Leaf cheaply.
The rate for those 4 hours is 5p or 6.5c/kWh compared to 14p or 18c normally, conversion as I'm in the UK!
In this position would you bother to mine during those 4 hours? I sold up all my GPUs and PSUs in 2018 apart from one 1070 and one 1060 3gb in two gaming rigs. I still have a 6 GPU motherboard.
Thanks for reading my pondering, and thoughts appreciated

Did you make the math about how much can you mine 4 hours daily in a month?
You have cheap electricity in those 4 hours, but I believe it's not enough to make some decent profits
Maybe if you have some GPUs os asics you could turn on, but for buy and expecting profits, I believe it's not worth the effort
