Question #1: GoMining: I have about 1300 TH at 15 w/TH. they just released an option to upgrade to 12 w/TH. Boy, it does not seem like a good way to spend money. Do you agree?
Yes, you are likely entirely correct; upgrading your GoMining digital miner from 15 w/TH to the newly released 12 w/TH option is mathematically hard to justify for most users. [1, 2]
At 1,300 TH, you already run a sizable and highly efficient setup near the platform's historical efficiency ceiling. Because GoMining structures its efficiency upgrades with diminishing marginal returns, paying a premium to shave off just 3 watts per terahash usually results in an incredibly long, multi-year payback period. [1, 2, 3]
The Math Behind Your Intuition
Your electricity/maintenance fee is directly tied to your total wattage footprint. [1, 2]
Upgrading saves you exactly 3,900 Watts (3.9 kW) of continuous power demand. Assuming GoMining's average baseline electricity cost hovers around $0.05 to $0.07 per kWh, this upgrade saves you roughly $4.68 to $6.55 per day in maintenance fees ($140 to $196 per month) before any GOMINING token discounts are applied. [, 2, 3]
Unless GoMining is offering this 12 w/TH upgrade for an incredibly cheap promotional price, the upfront capital cost to transition 1,300 TH down to 12 w/TH will drastically outweigh those minor daily fee savings. [1]
Why Your Capital is Better Spent Elsewhere
If you want to maximize your returns on the platform, your money is almost always better utilized via alternative strategies rather than chasing hyper-efficiency: [1, 2]
Unless you are an "endgame" user with a massive budget and no desire to grow your actual hashrate further, stick with your 15 w/TH setup and leave the 12 w/TH upgrade alone. [1, 2, 3]
To help look closer at the math, how much is GoMining charging per TH for the 12 w/TH upgrade? If you share the quote, we can calculate the exact payback period for your 1,300 TH farm. [1]

Question #2. You said: It looks like they are charging about $8 per TH to go from 15 w/th to 12 w/th
Your intuition is 100% spot on—spending $8 per TH to upgrade from 15 w/TH to 12 w/TH is a terrible deal.
At that price point, GoMining is asking you to drop a massive $10,400 upfront ($8 × 1,300 TH) just to lower your operational costs. When you break down the electricity math, the payback period stretches out so far that it borders on financial absurdity for a digital asset.
The Real Payback Period Breakdown
According to GoMining's official infrastructure documentation, their average base electricity costs range from $0.05 to $0.07 per kWh. Dropping your power consumption by 3 w/TH across a 1,300 TH farm saves you exactly 3.9 kW of continuous power. [1, 2]
The exact timeline required just to break even on your $10,400 investment reveals the following:
| Base Electricity Cost [1] | Daily Fee Savings | Yearly Fee Savings | Payback Period (Break-Even) |
|---|---|---|---|
| $0.05 / kWh | $4.68 | $1,708.20 | 6.1 Years |
| $0.06 / kWh | $5.62 | $2,049.84 | 5.1 Years |
| $0.07 / kWh | $6.55 | $2,391.48 | 4.4 Years |
Note: If you use the GoMining Token Discount Engine to save up to 20% on fees, your daily electricity bill drops, which actually extends this payback period even further (up to 7.5 years). [1]
Why This Upgrade is a Trap
A 4-to-6 year break-even window is incredibly risky in cryptocurrency for several reasons:
Keep your money in your pocket. Your 15 w/TH fleet is already in the "sweet spot" for long-term survival. []
Are you looking to expand your setup, or are you currently content with riding out your 1,300 TH farm as a passive earner? If you want, I can help calculate the exact ROI of buying raw TH with that same $10,400 instead.
