Your #1 issue is the cost of power. Anything over $0.10/kW/H will
NOT be able to mine at a profit. Period. No miner will ever be able to be efficient enough to do that.
Now if
BTC goes over $50k again then ja that
could work.
Your only option is to use a USB miner like
Sidehack's R909, pulls less than 100w for over 1.5TH. Use something like that and point it at a solo pool like Kano's or -ck's as a lottery miner. Dirt cheap to run and if it finds a block you get the entire reward.
I tried what you said using the USB miner from Gekkoscience, however the videos I watched showed that there is no win even with 3 of them, so I do not know how this would be a good idea after all.
Thank you for it anyways.
Actually, I would not mind if I would acquire BTC a bit more expensive using mining, for instance for the same power double the TH/s. The problem I would have right now would be the heat that is generated by it, and the noise. So I will think about this also.
Is there anywhere a calculation page where I could at least estimate what would be the loss, i.e. how much I would have to pay for the BTC?
Thank you
