Goldshell Mini-DOGE III+ Profitability — LTC+DOGE Merged Mining
Is the Goldshell Mini-DOGE III+ profitable?
The plus SKU of Goldshell's home line: 810 MH/s at 500 W (approx. manufacturer spec) — about 16% more hash than the Mini-DOGE III for 25% more power, so per MH it is actually slightly less efficient (0.62 vs 0.57 J/MH). You buy the III+ for more absolute yield in the same quiet class, not for better efficiency.
The only honest answer is a live one: revenue moves with LTC and DOGE prices and network hashrate every day. Same quiet class as the III, more absolute yield, slightly worse efficiency — whether the premium pencils out depends entirely on the tariff you type below. 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 — 810 MH/s | 810 MH/s · 500 W · 0.62 J/MH |
| Input power | 100–240 V standard outlet |
| Current draw | ≈4.2 A at 120 V — fine on a shared circuit |
| Heat output | ≈1,706 BTU/hr (500 W — all of it becomes room heat) |
| Noise | ≈35 dB (Goldshell claim, unverified) — quiet-fan class |
| 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.
