A GoMining discount might sound like a simple 20% reduction in operating costs.
But 20% of what?
The bigger your farm, the more OPEX you have. And the worse your energy efficiency (EE), the more electricity you consume per TH.
That means a 20% GoMining discount can be worth millions in annual savings for large farms. Let’s see how TH and EE change the value of the discount.
The Top 3 GoMining Farms
| Farm | Hashrate | EE | Annual saving from 20% discount |
|---|---|---|---|
| Monstr | 589,963.07 TH | 27.97 W/TH | ~$1.83M |
| 5601b81b | 411,639.15 TH | 19.97 W/TH | ~$988K |
| SHAMEN15 | 287,882.02 TH | 16.11 W/TH | ~$593K |
Using $0.05/kWh electricity, $0.0089/TH/day maintenance, and a 20% discount applied to both, the three farms represent approximately $3.41 million in annual savings.
These are theoretical calculations based on the stated TH and EE, not claims about their actual bills or discount status.
Why the GoMining Discount Matters More at Scale
The GoMining discount is a percentage, but the savings are measured in dollars.
More TH means more OPEX.
Therefore:
More TH → more OPEX → more value from the same discount.
The percentage doesn’t change.
The scale does.
How EE Changes the Value of the GoMining Discount
EE determines how much electricity you consume per TH.
A farm at 27.97 W/TH has significantly higher electricity costs than one at 16.11 W/TH.
That means worse EE creates a larger OPEX bill — and therefore a larger absolute saving from the same GoMining discount.
This doesn’t mean worse EE is better.
It means the discount has more OPEX to offset.
The GoMining Discount as a Partial Substitute for EE
This is the interesting part.
Better EE reduces electricity consumption.
A higher discount reduces the cost of the electricity and maintenance you still consume.
So a larger GoMining discount can partially compensate for worse EE.
It doesn’t eliminate the underlying efficiency disadvantage, but it can offset part of its economic impact.
Ideally, you want both:
Better EE + a large discount.
The Takeaway
The important question isn’t simply:
“What’s my discount?”
It’s:
“20% of how much?”
At small scale, the savings might be measured in hundreds of dollars.
At massive scale, the same 20% can be worth millions.
The bigger your farm, and the higher your OPEX, the more valuable that discount becomes.
But the objective isn’t simply to accumulate TH. It is to build a farm with sustainable economics – Build the Farm First.
