Meh, I've been thinking about powering up my mining rig once again, but Summer is coming so idk if it's even worth trying at this point. Might check out the XMR mining and give that a little try.
It has reached the point where you no longer are mining at a loss so you don't need to mine to heat your house to offset costs.
Basically as long as you got a basement or a garage then it shouldn't be an issue, especially with XMR. There are some people who have managed to get each GPU to use around 100 watts and it creates very little heat as compared to ETH mining.
You can also buy a 4U server chassis and put 6 GPUs inside and just vent the exhaust outside, or if you got a laundry room just create a Y adaptor and vent the heat there.
