Goldshell Mini-DOGE III Profitability — LTC+DOGE Merged Mining
Is the Goldshell Mini-DOGE III profitable?
The default answer to home DOGE mining: 700 MH/s at 400 W (approx. manufacturer spec), with a ≈35 dB noise claim that is the entire reason this box exists. It earns a fraction of an ASIC shelf — the trade is form factor for yield, and this page shows exactly what that trade costs per day at live network conditions.
The only honest answer is a live one: revenue moves with LTC and DOGE prices and network hashrate every day. The math below is deliberately unromantic: at 700 MH/s the yield is pocket change, and this page’s job is to show exactly how much before the quiet-fan premium feels justified. The break-even electricity figure is the line — pay less per kWh than that and the machine earns, pay more and it burns.
Why both coins count
Every serious Scrypt profitability number counts both reward streams. Through AuxPoW merged mining, the same hashes earn full Litecoin and full Dogecoin block rewards on one power bill — LTC-only math understates Goldshell Mini-DOGE III revenue by the entire DOGE share. The mechanics are on our LTC+DOGE merged mining calculator, which this page's math mirrors exactly.
Specs & physical reality
| Spec | Value |
|---|---|
| Factory bin — 700 MH/s | 700 MH/s · 400 W · 0.57 J/MH |
| Input power | 100–240 V standard outlet |
| Current draw | ≈3.3 A at 120 V — fine on a shared circuit |
| Heat output | ≈1,365 BTU/hr (400 W — all of it becomes room heat) |
| Noise | ≈35 dB (Goldshell claim, unverified) — quiet-fan class, the whole pitch of this box |
| Warranty | varies by brand, seller and region — get the term in writing before paying; used units typically carry none |
| Spec source | Goldshell — approx. manufacturer figures; real units vary by bin, firmware and temperature |
FAQ
- Does the Goldshell Mini-DOGE III mine LTC and DOGE at the same time?
- Yes — Scrypt machines merge-mine. The same proof of work is submitted to both chains, earning full rewards on each. Most major LTC pools credit DOGE automatically alongside LTC.
- What does the revenue figure exclude?
- Transaction fees on both chains (small next to subsidies, so figures are slightly conservative), cooling power, and difficulty drift. The 2027 Litecoin halving is a scheduled cut, not drift — the payback tile flags it when your horizon crosses it.
- How do I actually get paid in DOGE?
- Point the machine at a merged-mining pool — most major LTC pools (ViaBTC, F2Pool, Antpool among them) credit DOGE automatically alongside LTC. You mine one Scrypt job; the pool pays both coins to the addresses you set, on its normal payout schedule and fees. Nothing extra to configure on the machine.
