Just came back from a 4 months hiatus from the world of crytos. My GPU rigs have been asleep for the summer because of the heat. Right now, is it still possible to use a GPU rig in a manner that will be profitable? Or should I just dismantle them and sell the parts?
Since summer is over, same goes for a lot of people. Difficulty going to increase for all algo. So yeah GPU is useless for mining.
Not the case; I'm turning a profit at $0.11 USD per kWh.
Why do you always make posts similar to this, which inevitably leads to noobs asking you how you do so, to which you'll brag about the magic kernels that you've made and only you have access to? You give people false hope and waste time. It gets annoying.
That said, I don't think you should share your kernels and understand why you don't. Doesn't it get annoying having people beg you for them? If I were you I'd STFU about them and enjoy the extra profit, like I'm sure a good number of people do who may have just as good or even better custom kernels.
also 0.11 per kwh isn't something special, unless you are running mega farm, it's like mining air anyway
