6 GPU Rig (2x 1080ti's and 4 1080's) today making 0.033392 BTC a month or $198 a month before power bill on ZEC. Yikes!!! Was wayyy better when I started in Feb. Is 4168 Sol/s reasonable? Anything I can be doing better? Using SMOS. 35 months to break even at this rate :( .....HODL for a spike I suppose. BTW, the filtered box I built back in Feb/mar has worked fantastic. No overheating in 95F temps at times and the entire rig is super clean. The $5 filter was sooo dirty at 3 month mark. Reliably running on a cell phone connection using 60 mbs a day (not a small feat).
