From "Should I Mine?"
To Money In Your Wallet

It can be, but profitability is never guaranteed — it depends on hashprice, network difficulty, coin price, hardware efficiency and, above all, your electricity cost. As a rule of thumb in 2026, mining tends to work with power under about $0.10/kWh and current-generation hardware under roughly 15–20 J/TH. The sweet spot for home operators is $0.04–0.06/kWh. Always plan with best / base / worst-case scenarios.

Modern ASIC miners typically draw between 1,500 and 3,500 watts continuously, running 24/7. Electricity is the single largest ongoing cost — usually 75–85% of total operating spend. That's why your per-kWh rate matters more than almost any other factor in mining economics.

For a new high-efficiency ASIC in 2026, a realistic payback window is roughly 12–24 months at low electricity prices with Bitcoin at healthy levels. At higher power rates (€0.20/kWh+) payback can stretch to several years or never arrive. Hosted miners on our $0.07–0.08/kWh rates typically reach payback in about 12–18 months versus 18–28 months self-hosted. Use a profitability calculator with your real numbers before buying.

Profitability is dynamic. It moves with hashprice, difficulty, coin price, electricity cost, hardware efficiency and downtime. Newer, more efficient machines stay viable longer; older units get squeezed first as difficulty rises. Serious planning works with scenarios and assumes difficulty keeps climbing.

An ASIC (Application-Specific Integrated Circuit) miner is a computer built to do one job: run a single mining algorithm as fast and efficiently as possible. A Bitcoin ASIC runs SHA-256, computing trillions of hashes per second to compete for block rewards. Because the chips are purpose-built, ASICs are far more efficient than GPUs for the coins they support.

At minimum: a compatible ASIC miner, a mining pool account, and a wallet address for payouts. Practically you also need adequate power (most modern miners need a 240V circuit), cooling and airflow, a stable internet connection, and a plan for noise and heat. If you host with us, you only provide onboarding data (wallet, pool, worker) and we handle power, cooling and monitoring.

We stock ASICs by algorithm and use case: SHA-256 for Bitcoin, Scrypt for Litecoin and Dogecoin, KHeavyHash for Kaspa, plus Ethereum Classic, Aleo, Alephium and other algorithms. Availability depends on current batches and the market. Browse all ASIC miners →

We sell both, depending on stock. New units ship factory-sealed as an authorized reseller, with full manufacturer warranty. Used units are priced by model, condition and remaining warranty, and are assessed before sale. Your quote always states whether a unit is new or used.

Yes, for selected models. Pre-orders differ from in-stock items: delivery windows and market movements play a larger role, and the specific terms are stated clearly in your quote.

We serve both single-unit buyers and large B2B/project orders. For projects, share your model, quantity, delivery country, timeline and whether you want home or hosting, and we'll prepare a tailored quote. Phone and written quotes are available for B2B. Contact us →

In principle yes — depending on model, condition and market price. For an assessment we need the model, photos, location, runtime/condition and your target price.

Typically bank transfer and cryptocurrency; credit cards are usually not offered. The exact options appear in your checkout or quote. For larger amounts, verify payment details through a second channel and only use the details on the official quote.

It depends on your delivery country, shipping method and local import rules. In many cases import VAT and customs duties apply. With DDP shipping these are handled up front, so there are no surprise charges on delivery. See Shipping info →

Home mining gives you full control but means dealing with 80+ dB noise, heat, 240V wiring and your own maintenance. Hosting puts your miner in a professional facility with industrial power, cooling, security and repairs handled for you. Most home operators find hosting cheaper once they factor in electricity, cooling and downtime. You keep full ownership of the hardware either way.

Air-cooled ASIC miners are loud — typically 75–85 dB, similar to a vacuum cleaner running constantly. This is the number-one surprise for home miners and makes living spaces impractical without a dedicated room, garage or shed. Hydro (water-cooled) miners are much quieter, and hosting removes the noise issue entirely.

Most high-efficiency ASICs require a 240V circuit, not a standard 120V household outlet. A 240V supply is also more efficient and draws fewer amps, reducing breaker-tripping risk. A common safe setup is a 240V/20A circuit with a double-pole breaker, 12 AWG wire and a NEMA 6-20R outlet. Always have a licensed electrician verify your install before running continuous high load.

Air-cooled miners need strong, continuous airflow and a way to exhaust hot air out of the space. Hydro (water-cooled) miners use a closed coolant loop with radiators or a CDU and dry cooler — they run cooler and far quieter at higher density. Immersion cooling submerges hardware in dielectric fluid. Hosting handles all cooling for you. Explore hydro miners →

It depends on the model and power draw. What matters is the correct plug type for your region, properly sized (gauge) cables for continuous load, and secure circuit protection. Under-rated cabling is a fire risk at 24/7 high wattage — when in doubt, consult an electrician.

You buy or ship miners to us; we receive, inspect and install them in a regulated US facility, connect them to power and your pool, and you monitor everything live via dashboard and mobile app. We handle cooling, security and repairs. Hosting starts at $0.07/kWh for enterprise (50+ miners) and $0.08/kWh standard, billed on actual kWh, with a free 24-hour trial. See our regulated farms →

Yes — you retain full hardware ownership. Your miner is your property forever; we only operate and maintain it on your behalf inside our regulated facilities.

We've maintained 99.9% uptime since 2020 across four US facilities (95 MW total), with redundant power, backup generators and 24/7 on-site security. On-site repairs of fans, hashboards and PSUs are free — no shipping, no downtime billing. Verified hosting clients can book a facility tour.

DDP (Delivered Duty Paid) means the seller handles export, import clearance, duties and taxes, delivering the miner to your door with nothing extra to pay on arrival. It removes customs uncertainty and surprise fees — you know your landed cost in advance. We offer DDP to many destinations; availability is confirmed in your quote.

We ship to the US, Europe, the UAE and most countries worldwide, depending on device, stock, carrier and local import requirements. Any restrictions are clarified in your quote before you order.

In-stock items are dispatched promptly after payment is received. Transit time depends on the carrier and destination, and you receive tracking once shipped. For pre-orders, the delivery window in your quote applies.

Once shipped, you receive tracking information or a dispatch update. For pre-orders or incoming batches, you get status updates according to the delivery window stated in your quote.

Create a wallet to receive payouts (a hardware wallet like Ledger/Trezor for security, or a software/exchange wallet), then choose a mining pool and create a worker. In the miner's dashboard under Pool Settings, enter the pool URL, your worker/username and password, and ideally configure two backup pools for failover. We offer setup assistance for pool/worker configuration.

Open the miner's network settings, switch IP allocation from DHCP to Static, and enter an IP, gateway and subnet on your network. A static IP makes each miner easy to identify and keeps the connection stable. For many units at once, manufacturer tools (e.g. APMinerTool) can batch-assign static IPs across an IP range.

No — stability matters far more than speed. Mining uses very little bandwidth; what counts is a reliable connection with few interruptions so your miner stays connected to the pool.

Standard process: (1) select model and quantity, define target coin/algorithm; (2) confirm hosting availability and terms; (3) submit onboarding data — wallet and pool/worker; (4) go-live with a functional test (hashrate/temps) and monitoring access; (5) ongoing operation with maintenance and replacement per your package.

User manuals and specifications are available directly from the manufacturer's support section, and we link the important details on each product page. If you're stuck, our support can point you to the right resource.

New hardware carries the manufacturer's warranty under their terms. For hosting, additional processes apply: diagnosis, repair/RMA and replacement depending on your package. For used hardware, warranty depends on the remaining term. Your quote states the applicable warranty.

For hosted miners, on-site repairs of fans, hashboards and PSUs are performed free of charge — no shipping, no downtime billing. For home units, we support diagnosis and guide you through warranty/RMA with the manufacturer where applicable.

Yes. Typical topics include pool/worker configuration, monitoring basics, diagnosing hashrate drops and general troubleshooting. Reach us via WhatsApp, Telegram, email or the contact form.
