Actually I have the same "problem".
I have free electricity (and 280X graphics cards that I am using only for gaming right now) but I turned off my rigs in summer because it was too hot in my room. So I need to know what to mine that it is worth suffering noise (as heat is no more a problem).
I do not understand why you're doing problems about what to mine, if you have free electricity ..
although, if you mine the less profitable coin, you will always have a gain ...
no?
?
Because rigs require "some" time. They have to be checked, rebooted, there are issues that pop up. Pools go down, coins go down. Nothing is just set and go.
So while i have 60 280x cards... My question was, if its 10 cents a day, rational, because for 6 bucks a day its not worth my time.
Thanks to those who provided input!
