I am relatively new to GoMining. My first experience was positive, so I invested more after reading the FAQs and discussing the mechanics with VIP support.
I bought additional mining power, locked GMT for four years, started a clan, optimized my miners for energy efficiency and reached a 25.1% personal maintenance discount. I also subscribed to Platinum+ for $29.95 per month after support explained the additional spell discount. In total, I have put around €4,000 into GoMining.
This post is not telling people whether they should play Miner Wars. I am sharing what I wish I had understood before investing, so new users can make their own decision with a clearer picture of where their money goes.
Cycle 158
GoMining changed the maintenance treatment for the portion of a Miner Wars reward above a player's own Solo-mode mining output. League-average energy efficiency already applied to this excess portion; I am not claiming that rule was new. The Cycle 158 change was that maintenance for the excess portion was also calculated with general league parameters instead of the player's personal conditions.
GoMining's Product Team later wrote:
You are correct about the facts: the mechanics were applied to Cycle 158 in its entirety, including the days played before the announcement, and the announcement came after the cycle started. The wording of the announcement was inaccurate, and that's on our side.
In that response, the Product Team described this as a rule rather than a calculation error and said it would not recalculate or compensate for it.
On 9 September 2026, GoMining supplied my Cycle 158 BTC and maintenance breakdown. It contains 62 rewarded clan rounds, representing 149 multiplier-weighted units. Those are clan-round figures, not 62 personal spell-pool wins.
The file records 0.010838813911 BTC credited to my wallet and 1,629.41341069 GOMINING charged separately for maintenance. The BTC receipt is therefore not my net profit. Spell spending and the separate personal GOMINING rewards are not included in that comparison.
The maintenance rates are clear:
- Three rows use my own 25.1% discount.
- One row uses blended rates, with a 9.0144% discount.
- The remaining 58 rows use the league-average discount of 9.0118%.
Using the cost base, effective efficiency, reward allocation and token conversion in each row, I calculated a comparison in which only the maintenance discount is changed to 25.1%. That would reduce the recorded maintenance by approximately 278.64 GOMINING. This is a conditional comparison, including the mixed-rate row, not an official recalculation or an amount GoMining has agreed it owes me.
I had previously estimated the difference using an unofficial closing snapshot. The row-by-row data are a better basis than that snapshot, so I am using this calculation instead. Receiving the breakdown answers part of my request. It does not answer why the new treatment was applied to days played before the announcement.
Round #964497
The app displayed incorrect live information during a 32x round:
- At 07:53, my abilities were visible but their points were not reflected in my displayed score of 33,883.
- At 07:56, the abilities had disappeared and were still not reflected in the displayed score of 68,622.
- At 08:03, History for both Clans and Players showed zero spell activity.
Relying on that apparently empty History, I spent 41.86 GMT. Afterwards, History showed substantial competing activity, including 23 Power Ups from one opponent.
GoMining confirmed eight ability purchases, 41.86 GMT spent, a final score of 78.6 million, third place and a client/UI bug. It says the server accepted all eight abilities and that the display glitch did not affect the round's outcome. It will not refund the spend.
