JingleMiner LTC-DOGE Hashcard 600MH

The Hashcard delivers 600 MH/s (0.6 GH/s) of Scrypt hashrate at 160W wall draw and 0.267 J/MH efficiency. JingleMiner rates the unit with plus or minus 10 percent hashrate variance typical for compact form factor hardware. Real world output typically ranges from 540 to 660 MH/s depending on ambient temperature (keep below 38 degrees Celsius for rated output), voltage stability, and pool connection quality. Released December 2025 as the most compact dedicated Scrypt ASIC currently available.

The Bitmain Antminer L9 produces approximately 17 GH/s at 3,570W, roughly 28 times the Hashcard's hashrate at 22 times the power draw. The L9 is industrial hardware targeting professional mining operations. The Hashcard is desktop hardware targeting home miners and hobbyists. These products serve completely different market segments. If you run a professional mining operation with industrial electrical service and dedicated facility space, the L9 or Bitdeer SEALMINER DL1 Air delivers better absolute economics. If you want to mine LTC and DOGE from a home office or bedroom without infrastructure changes, the Hashcard is one of the few viable options.

Depends on your definition of meaningful. At MillionMiner's onsite $0.08 per kWh calculator, the Hashcard produces $0.41 daily revenue, $0.31 electricity cost, and $0.10 daily net profit. Monthly net: approximately $3. Annual net: approximately $36. For industrial operators, those margins are irrelevant. For home miners who value the learning experience, wallet accumulation, and the satisfaction of producing their own Litecoin and Dogecoin, the Hashcard produces a few dollars monthly at near zero infrastructure cost. The economic framing that matters is not "will this make me rich" but "will this teach me mining mechanics and let me accumulate meaningful amounts of LTC and DOGE over time."

Any Scrypt algorithm cryptocurrency. Litecoin (LTC) is the primary target and largest Scrypt network. Dogecoin (DOGE) merge mines alongside LTC through supporting pools without splitting hashrate. Bellscoin (BELLS), Junkcoin (JKC), Luckycoin (LKY), and Pepecoin (PEP) also join the merged Scrypt stack through appropriate pools. Combined merged mining revenue typically runs 20 to 40 percent above solo LTC mining at the same hashrate. Configure your pool and wallet through the web interface.

LitecoinPool is the longest established Scrypt pool with full merged mining support for all compatible coins and low fees. F2Pool offers broad multi algorithm coverage. ViaBTC supports merged mining with accumulation mode payouts that reduce variance. AntPool provides strong pool hashrate and reliable uptime. Prohashing offers auto profit switching between Scrypt coins based on real time profitability. Pool fees typically range from 0.5 to 2 percent. For home miners with 600 MH/s hashrate, lower payout thresholds matter because you want reasonable payment frequency rather than waiting months to reach minimum payout.

Setup takes under 10 minutes. Step one: plug the 12V adapter into the Hashcard and into any standard outlet. Step two: connect Ethernet cable from the Hashcard to your router, or use the Wi-Fi setup described below. Step three: power on and wait 60 seconds for boot. Step four for Ethernet: find the miner IP through your router's DHCP client list. Step four for Wi-Fi: connect your phone or laptop to the JingleMiner_XXXX Wi-Fi network the device broadcasts, then enter your home Wi-Fi credentials. Step five: open the miner IP or the configuration page in any web browser. Step six: enter your Scrypt pool URL in stratum+tcp format (for example stratum+tcp://litecoinpool.org:3333), your Litecoin wallet address as the worker name, save, and hashrate reaches 600 MH/s within 5 to 10 minutes.

Standard 12V DC input through the included adapter, which plugs into any standard 100 to 240V household outlet. The included 12V adapter handles voltage conversion automatically for North American, European, Asian, and Middle Eastern grids. Total draw is 160W continuous, comparable to a gaming laptop or mid sized monitor. No dedicated circuit required. No 240V service needed. No electrical panel work. The Hashcard is the rare professional grade Scrypt ASIC that genuinely works with standard household electrical infrastructure everywhere in the world.

40 dB sits at the noise level of a quiet refrigerator hum or a modern desktop computer fan at moderate load. Meaningfully quieter than normal conversation (60 dB) and dramatically quieter than industrial mining hardware (75 to 80 dB). Deploy on a desk during work hours, in a bedroom corner at night, on a living room shelf during family time, in a kitchen counter alongside other appliances, or in any indoor environment where you can tolerate a computer fan running continuously. No sound isolation required. No dedicated rooms needed. The 40 dB operating level is the primary design differentiator for home Scrypt mining.

Yes, with linear scaling and no fleet management complexity. Two cards produce 1.2 GH/s at 320W. Five cards produce 3 GH/s at 800W. Ten cards approach 6 GH/s at 1,600W. Each card operates independently with its own IP address, pool connection, and worker name. Standard consumer routers handle dozens of connected devices without problems. Electrical infrastructure scales linearly: at 160W per card on 120V, a standard 15 amp residential circuit handles roughly 10 cards before hitting safe continuous load limits. For deployments above 10 cards, distribute across multiple circuits or use 240V service.

Goldshell Mini Doge series (Mini Doge Pro, Mini Doge II) produces 205 MH/s to 420 MH/s at 215W to 250W, competing with the Hashcard on the home Scrypt mining segment. The Hashcard leads on hashrate at 600 MH/s and matches on form factor. ElphaPex DG series targets industrial Scrypt mining at GH/s scales that exceed the Hashcard's segment entirely. For home miners comparing compact Scrypt options, the Hashcard offers meaningfully more hashrate per unit than Goldshell alternatives in similar form factors. For operators wanting industrial scale, neither the Hashcard nor Mini Doge serve that market.

JingleMiner supports both Wi-Fi 2.4G and Ethernet connectivity. For best reliability, Ethernet is recommended because hashrate can drop when Wi-Fi signal becomes unstable. If you must use Wi-Fi, place the Hashcard within 10 meters of your router with minimal physical obstructions. Performance mode typically stays within rated hashrate on stable Wi-Fi. For deployments where hashrate consistency matters, connect through Ethernet even if the physical cable run is inconvenient. The reliability gain outweighs the setup hassle for continuous 24/7 operation.

Specific buyer profiles fit the Hashcard. Home miners who want to accumulate LTC and DOGE with their own hardware without dedicating rooms or installing dedicated electrical circuits. Hobbyists and crypto enthusiasts who value running mining infrastructure over maximizing daily revenue. Educators teaching mining mechanics at minimal infrastructure cost. Apartment dwellers who cannot deploy industrial hardware due to noise or power constraints. Beginners learning pool configuration and wallet management before scaling to larger hardware. Fleet operators stacking 5 to 20 cards to create a quiet home mining setup with linear scaling. For operators targeting professional mining economics, the Antminer L9 or Bitdeer SEALMINER DL1 Air is the correct answer.

Minimal. Monthly dust removal with compressed air through the intake vent to maintain cooling efficiency. Quarterly inspection of the single cooling fan for unusual noise or reduced RPM (warning signs of bearing wear). Semi annual firmware updates when JingleMiner releases patches through the web interface. Continuous ambient temperature monitoring to keep the unit below 38 degrees Celsius for rated hashrate output. The simple single fan cooling architecture and low thermal load make the Hashcard one of the lowest maintenance mining devices available, comparable to keeping a gaming PC clean.

JingleMiner produces multiple compact mining devices. The LTC-DOGE Hashcard (this product) covers Scrypt mining at 600 MH/s. The BTC Hashcard at 12.5 TH/s covers Bitcoin SHA-256 mining in a compact form factor. The BTC SOLO Mini Lottery Miner at 300 KH/s and 1W is a hobbyist lottery mining device. The Fluminer L1 Pro at 6 GH/s covers higher output Scrypt mining in a slightly larger home server format. JingleMiner's product philosophy consistently targets compact home and desktop mining hardware rather than industrial scale ASICs, which is the category where the company has built its reputation.

Alternatively, use the Get a Quote button to contact MillionMiner sales directly for estimated restock timing and priority reservation on incoming batches. JingleMiner products ship in smaller batch quantities than industrial hardware because the target market is narrower, so stock moves quickly when batches arrive. Global demand has been consistent since the December 2025 launch.

JingleMiner's firmware includes a performance mode that pushes output above standard spec when ambient temperature stays below 38 degrees Celsius. Aggressive overclocking beyond performance mode is not supported through stock firmware and would risk thermal damage to the compact chassis design. The Hashcard's power and thermal envelope is tuned conservatively for home deployment reliability rather than peak overclocked performance. Operators wanting maximum Scrypt hashrate per unit should look at industrial hardware like the Bitmain Antminer L11 Hyd 2U or Bitdeer SEALMINER DL1 Air rather than trying to squeeze extra output from compact desktop cards.

At 160W and minimal infrastructure cost, the Hashcard stays profitable at electricity rates far higher than industrial hardware can tolerate. The practical breakeven for daily electricity to match daily revenue at 600 MH/s depends on LTC and DOGE prices and network difficulty, but at current April 2026 conditions the Hashcard produces positive margin even at $0.20 per kWh residential rates. If Scrypt mining becomes fundamentally unprofitable (deep bear market with very high network difficulty), the Hashcard's low power draw means shutting it off is simple and retains resale value on secondary markets.

Igen, valóban. A Hashcard gyakorlati betekintést nyújt az ASIC bányászat mechanikájába minimális költséggel és összetettséggel. Annak, aki a proof of work kriptovalutákról, a pool konfigurálásáról, a pénztárcák kezeléséről és a bányászat gazdaságáról tanul, kevés eszköz tanít olyan hatékonyan, mint a valódi hardver futtatása. A 600 MH/s kimenet idővel elegendő LTC és DOGE nyereséget termel, hogy a pénztárcák egyenlege jól láthatóan növekedjen, így erősítve a tanulási élményt. A 40 dB zajszint és a 160W energiafogyasztás valóban praktikus működést tesz lehetővé bármilyen otthoni környezetben, szemben az ipari hardverrel, amely dedikált infrastruktúrát igényel. A hobbi vásárlók, oktatók és szülők, akik tinédzsereknek szeretnék oktatni a kriptovaluta-bányászatot, mind megtalálják a Hashcardban a számukra ideális megoldást.

JingleMiner provides 180 day manufacturer warranty covering the first six months of hardware defects under normal operation within specified environmental ranges. Warranty covers manufacturing defects, component failures, and firmware issues. It does not cover damage from improper power supply use, operation outside the 5 to 40 degree Celsius range, physical damage from mishandling, or unauthorized firmware modifications. MillionMiner routes warranty claims through direct JingleMiner channels for faster resolution than secondary market purchases provide.

For home operators comparing compact Scrypt options, look at Goldshell Mini Doge Pro and Mini Doge series at 205 to 420 MH/s for lower hashrate alternatives at comparable form factor. For the next step up from home mining to semi professional scale, the Bitdeer SEALMINER DL1 Air at 25 GH/s covers industrial Scrypt deployment at 3,725W, though it requires the infrastructure the Hashcard avoids. The Bitmain Antminer L9 series at 17 GH/s covers established Scrypt mining operations. For operators combining compact home Scrypt mining with other algorithms, pair the Hashcard with the Jingle Miner BTC Solo Lite or similar hobbyist Bitcoin hardware for multi algorithm home deployment. MillionMiner's ASIC hosting service does not typically accept Hashcard scale hardware because economics favor the industrial scale DL1 Air or L9 deployment instead.
