GMT Flywheel Calculators

Plan a GoMining Flywheel three ways. Enter your farm and the GMT you hold once below; each tab applies a different strategy to the same numbers and tells you what to add.

Saved setup

My Farm

Start here: enter your hashpower and efficiency.

Total Hashpower 20.00 TH

Efficiency 12 W/TH

12W = current floor tier · 15W = legacy

Miners at different efficiencies? Enter each miner

GoMining charges each miner at its own W/TH. List them here and the two boxes above are filled in for you: TH added up, efficiency averaged by TH. That gives the same daily cost as GoMining's per-miner total.

Liquid Days 0

Enter what you hold today. Leave a box empty if you have none. "Days" = days of maintenance your GMT covers, as on GoMining's Maintenance Discount page (counted after your VIP, service and mining-mode discounts, before the token discount). Days and GMT are two views of the same amount: type in either one and the other updates. The one you edited last stays fixed when the GMT price or farm settings change.

The Flywheel's Targets

Locked Days —

Unlocked Days —

Unlocked While Building —

Until the locked side reaches its target, keep only about this many days unlocked (DracoF: 14) and lock the rest for the maximum period.

Total target—

Optional: buy miners when total is—

Optional: sell extra miners when total is—

Defaults are DracoF's 360 locked / 140 unlocked = 500 days. "Days" are GoMining's maintenance days for your farm, as on the Maintenance Discount page.

Weekly Checklist

DracoF's advice: decide no more than once a week, on the day your lock dividends arrive (usually Tuesday).

Formula reference

The rules (DracoF's Flywheel)

lock GMT worth 360 days for the maximum period; keep 140 days liquid; total 500
below 500 total days, or while building: reinvest in GMT.   above 500: reinvest in TH or take BTC
above 640 total days (optional): buy miners with unlocked GMT.   below 360: sell extra miners

Days, GMT and the price cushion

days = GMT ÷ (daily maintenance after your VIP, service and mining-mode discounts)
price cushion = 1 − 360 ÷ total days      (how far GMT can fall before total days drop under 360)

Maintenance is priced in dollars, so your days shrink in step with the GMT price; the unlocked buffer exists to keep the 20% token discount through a fall. The GMT to acquire is the fewest extra days of GMT that satisfy both targets, since unlocked GMT can be locked but locked GMT cannot be unlocked.

Above this, stop buying TH and start taking profits. Audacity's own line is $100k; set yours.

TH Ask Price $/TH

GoMining's price for new TH at your efficiency. Estimated from Audacity's July 2026 numbers ($12.53 at 15 W/TH plus $2.67 per W/TH of upgrade, about $20.54 at 12 W/TH). Type GoMining's current price to replace it.

Greedy Machine Growth %/week

Free weekly TH growth (DracoF: about 0.16%, or 8.7% a year).

Audacity's Plan

Buy into weakness, sell into strength. Not financial advice: the cutoff and the discounts are assumptions you set.

Formula reference

The split (Audacity's Modified Flywheel)

hold 400 days locked (max period) and 100 days unlocked (as low as 50 for a good deal)
the days, GMT to acquire and stage are worked out exactly as on the Traditional tab

TH per $1 of earnings

direct:       (1 + VIP bonus) ÷ GoMining ask
marketplace:  (1 − 2.25% GMT reinvest fee) ÷ (ask × (1 − marketplace discount))

The VIP bonus is +5% from Silver I and +10% from Diamond I; GoMining charges a 2.25% fee when earnings are reinvested into GMT, and sellers (not buyers) pay the 5% marketplace fee. With a 20% discount, a 5% bonus and the 2.25% fee the marketplace gives about 16% more TH, matching the write-up's "about 15%".

Greedy Machine break-even

years = ln(1 + premium) ÷ (52 × ln(1 + weekly growth))
TH growth after n years = (1 + weekly growth)^(52 n) − 1

This ignores the extra maintenance the growing TH needs, so the real break-even is longer. The BTC cutoff is a personal rule, not a prediction.

Target & Lock

OPEX Coverage Target 125%

Lock Period Max

Votes = GMT locked × time left ÷ 4 years. A lock's votes decay weekly unless you re-extend it, and this model assumes you keep it at this period.

—

Locked GMT: now vs. required (locking all your liquid GMT) —

Plan	Required Locked GMT	Token Discount	Lock APR	From Your Liquid	GMT to Buy

Lock Period (lock all)	Required Locked GMT	Lock APR	GMT to Buy

Formula reference

Daily maintenance per TH (at 0% discount)

elec_0 = (kWh_rate × 24 × W/TH) / GMT_price / 1000
service_0 = service_constant / GMT_price
perDay_0 = TH × (elec_0 + service_0)                  (GMT/day, whole farm)

Token discount (automatic) and total discount

maint_days = (locked_GMT + liquid_GMT) ÷ (perDay_0 × (1 − VIP − service − mining))
token_discount = min(20%, floor(maint_days ÷ 18) × 1%)
weekly_OPEX_GMT = 7 × perDay_0 × (1 − token − VIP − service − mining)

Both locked and liquid GMT count toward the token discount, which is why locking liquid GMT costs you nothing there. The "days" figure is measured after your non-token discounts (this matches GoMining's own Maintenance Discount page).

Lock rewards (GoMining veGOMINING model)

votes v = GMT_locked × (time_left ÷ 4 years)
weekly_reward = POOL × v ÷ (T_others + v)
APR = (365 ÷ 7) × weekly_reward ÷ GMT_locked

Fitted to GoMining's own Lock Calculator: it reproduces its weekly reward within 0.01% for locks from 1 to 10,000,000 GMT and its APR at every lock period. POOL and total votes change every week and are refreshed automatically. T_others is total votes minus your current lock's votes.

Required lock

for each possible token-discount tier k = 0..20:
  needed_dividend_k = target × 7 × perDay_0 × (1 − k% − VIP − service − mining)
  v_k = needed_dividend_k × T_others ÷ (POOL − needed_dividend_k)
  L_k = max(v_k ÷ time_fraction, 18k days of maintenance − GMT_kept_liquid)
required_locked = the smallest L_k

Holding more GMT raises your token discount, which lowers your costs, which lowers the lock you need, so every tier is tried and the cheapest one that works is used. "Lock all" also puts your liquid GMT into the lock.
