What is the average energy cost per month of the S19 mining machine?
Well, that depends on a variety of variables including, but not limited to, location, single or three phase, ambient heat in the mine (air flow model), availability of alternate energy resource vendors as well as a bit closer to home, variables like how the host is managing the equipment.
Since February of 2021, data centers that are not mining using exclusively renewable energy sources are absorbing utility rate increases as a result of the rampant energy (and everything else) price inflation permeating across the greater US economy.
If you are an individual miner who is just delving into mining it can be difficult to find a host who will take on only one machine that you can trust. That is a big part of why BitcoinU is here - to be a conduit, enabling the greater masses an opportunity to enter into a lifetime of BTC mining.
Currently, a Bitmain Antminer S19jPro 104TH mines at 3,068 watts.
At $.095 per kWh the daily electricity cost is roughly $7.40 (4-1-22) and monthly is $222.00 (30 days). At today's network difficulty 27+T (which is just south of as high as it has ever been) that leaves a net daily income stream of between $13.50 - $14.00 daily, per ASIC, after an average 7% admin fee.
