New Guy here. Context: I have 3 6 GPU mining rigs I built last summer for altcoin mining. The rigs I have are from these instructions with Z270-As and nvidia 1070s. I'm not running Windows like they are though.
The hardware is all paid off, but profits are getting thinner every day. Here's the mining alternatives that I have heard people doing so far:
Folding - which I just started to learn about today
Selling GPU time for rendering jobs - there seems to be more talk about this than actual activity
Continue Mining - this is what I'm currently doing
Sell the Mining Rig - sell the hardware while it still has some value (especially since it has paid for itself and then some).
What are the miners here leaning towards?
