My real GoMining numbers after building a 254 TH fleet — costs, BTC output, maintenance and what I’ve learned
I've been using GoMining for a while now and thought it might be useful to share some actual numbers rather than another "is GoMining legit?" post.
This isn't financial advice and I'm not claiming this is better than simply buying BTC. GoMining has platform, mining, token and counterparty risk that holding BTC yourself doesn't have.
CURRENT SETUP
My fleet is currently:
• 254.19 TH total
• 12 W/TH efficiency across the fleet
• 6 miners
• Platinum III VIP
• 26.59% maintenance discount
• BTC rewards accumulated in my GoMining wallet and periodically moved out
• I also participate in GoMining governance by locking GOMINING tokens
My objective is fairly simple:
Build a mining setup that eventually pays its own maintenance and continues accumulating BTC without needing regular new cash from me.
LATEST REAL NUMBERS
My latest daily mining reward was:
0.00010966 BTC
That's about 10,966 sats for that reward.
My wallet currently contains:
0.00438582 BTC
I'm using 0.005 BTC as my withdrawal/sweep point, so I'm getting fairly close to another one.
I've also got USDT held in Simple Earn, currently showing 11.27% APR in the app, which provides some additional BTC rewards while the money is waiting to be used.
TODAY'S EXPANSION
I just added another 32 TH to one of my existing miners.
Before:
2.1484 TH
After:
34.15 TH
Cost:
494.52 USDT
Price:
$15.45/TH
Efficiency remains:
12 W/TH
The app estimated the miner's daily reward moving from:
0.00000106 BTC/day
to
0.00001685 BTC/day
So the incremental 32 TH is initially adding roughly:
0.00001579 BTC/day
= 1,579 sats/day
At today's rate that's roughly 576,000 additional sats/year, although obviously nobody should extrapolate that unchanged for years because mining difficulty, halvings, fees and network hashrate will change.
WHY I BOUGHT THE UPGRADE RATHER THAN ANOTHER MINER
Interestingly, GoMining was offering me a new 32 TH / 12 W/TH miner at about $16.59/TH.
The upgrade was $15.45/TH.
So I upgraded one of my small miners instead.
I've also decided that future expansion will generally be capped at around 32 TH per purchase rather than continually buying huge miners.
That gives me much more control over capital deployment.
THE PART I THINK PEOPLE OFTEN MISS: MAINTENANCE
I don't look at TH purchase price alone.
Every extra TH also creates additional maintenance requirements.
My approach is therefore to look at the "fully supported cost per TH":
miner/upgrade cost
+
the additional governance/flywheel capacity needed to help cover its maintenance.
I lock GOMINING tokens and receive governance rewards. The longer-term objective is for governance rewards to cover roughly 2x my maintenance requirement.
I'm not fully at that target following today's expansion, so I'm deliberately stopping TH purchases for now and allowing the governance side to catch back up.
In other words, I don't regard cheap TH as automatically being a good purchase.
BTC PRODUCTION WILL DECLINE
I'm also not modelling today's BTC/TH forever.
Bitcoin halvings reduce block subsidy and network difficulty/hashrate changes over time.
However, I don't think assuming mining output simply collapses towards zero is realistic either.
Difficulty adjusts, inefficient miners leave, transaction fees contribute to mining revenue and the network reaches new economic equilibria.
So I expect BTC per TH to decline over the long term, particularly around halvings, but not disappear.
That's one reason I've concentrated on getting the entire fleet to 12 W/TH.
WHAT I LIKE ABOUT GOMINING
• Actual BTC accumulation is satisfying and measurable
• No physical ASICs sitting in my house
• 12 W/TH efficiency is available
• Miners can be expanded in relatively small increments
• Governance rewards can offset some operating costs
• BTC production gives me a different accumulation mechanism from simply buying BTC
• There is a marketplace/resale mechanism
WHAT I DON'T LIKE / RISKS
• You're dependent on GoMining as a company/platform
• You're exposed to mining economics and Bitcoin difficulty
• GOMINING token economics matter if you use the governance system
• Maintenance never disappears
• It's more complicated than buying BTC and putting it in cold storage
• Attractive ROI figures in the app shouldn't be treated as guaranteed returns
• It's very easy to get tempted into continually buying more TH
That final point is probably the biggest lesson I've learned.
Cheap TH can make expansion addictive.
I've now imposed a rule on myself:
Get the existing mining engine properly supported before adding more.
WHAT I'D TELL SOMEONE STARTING TODAY
I wouldn't start with a massive miner.
I'd start small, choose 12 W/TH if the economics make sense, watch the actual BTC and maintenance flows for a few months and learn how the system works.
And I'd compare every proposed purchase against the simplest alternative:
"What happens if I just buy the equivalent amount of BTC instead?"
Sometimes the miner wins on my assumptions.
Sometimes BTC wins.
I don't think anyone should automatically assume one is better.
I'll probably post periodic updates with actual BTC production, maintenance, governance rewards and whether my self-sustaining mining experiment is working.
Happy to answer questions about the numbers or show screenshots of anything useful.
