ASIC Miners for Sale: Buy Bitcoin, Kaspa, Litecoin and Altcoin Mining Hardware

ASIC stands for Application-Specific Integrated Circuit, a chip engineered exclusively for one task: computing a specific cryptocurrency hashing algorithm as fast and efficiently as possible. Unlike a GPU, which is a general-purpose graphics chip, an ASIC does nothing else. This makes ASICs 10–100x faster and 20–50x more energy-efficient than GPUs. The trade-off: an ASIC for SHA-256 (Bitcoin) cannot mine Scrypt (Litecoin) or any other algorithm, it is completely single-purpose.

We stock the full current-generation range from Bitmain Antminer, MicroBT WhatsMiner, Canaan Avalon, IceRiver, iPollo and Goldshell. Browse our Bitcoin miners (SHA-256)Dogecoin & Litecoin miners (Scrypt)Kaspa miners (KHeavyHash), and hydro-cooled miners. All units sourced directly from manufacturers or authorized distributors.

Yes, we offer free worldwide DDP shipping on all orders. DDP means we handle export, international freight, import customs clearance and duty payment. You receive your miner with no unexpected charges. In-stock units ship within 1–3 business days; delivery takes 5–14 business days depending on destination.

Efficiency, measured in joules per terahash (J/TH), is the key factor. At $0.05/kWh or lower, most current ASICs are profitable. At $0.08–$0.12/kWh, focus on flagship models like the Antminer S23. Above $0.12/kWh, consider MillionMiner hosting at $0.07/kWh for guaranteed lower costs. Use the profitability calculator on each product page.

You need: a dedicated 16A or 32A electrical circuit, a standard Ethernet connection, and a well-ventilated space, ASICs generate significant heat and run at 70–80 dB. A garage, basement or utility room works well. Setup takes under 10 minutes. Alternatively, skip home setup entirely with professional hosting

New Bitmain Antminer units carry 180-day manufacturer warranty. MicroBT WhatsMiner: 180 days. Canaan and IceRiver: 180–365 days depending on model. For miners with MillionMiner hosting, we additionally provide free on-site repairs and full RMA handling. See our FAQ for full warranty details.

You can mine any coin that uses the same algorithm. A Scrypt ASIC can mine both Litecoin and Dogecoin simultaneously via merged mining. A SHA-256 ASIC can mine Bitcoin, Bitcoin Cash, or any SHA-256 coin. However, a SHA-256 ASIC cannot mine Scrypt or KHeavyHash coins, the algorithm is the compatibility boundary.

DDP (Delivered Duty Paid) means MillionMiner takes full responsibility for getting your miner to your address, including export, freight, customs and import duties. Import duties on mining hardware can add 10–20% in many countries. With our free DDP shipping, the listed price is the final price, no surprises.

The Bitmain Antminer S23 (318 TH/s, ~15 J/TH) is the most efficient Bitcoin miner available. The Antminer S21 XP (270 TH/s) and S21 Pro (234 TH/s) are excellent alternatives at lower price points. For water-cooled setups, the Antminer S23 Hydro (580 TH/s) delivers maximum hashrate per unit.

Yes. Purchase your miner from our shop and add professional hosting, we deploy it directly into our verified U.S. data centers from $0.07/kWh. Every customer gets a real-time dashboard, 24/7 support, free on-site repairs and a free 24-hour trial. 1.79 EH/s of hashpower currently hosted across our U.S. facilities.

The Antminer S23 consumes ~4,700W, the S21 Pro uses 3,510W, and smaller miners like the Goldshell KA Box use just 400W. At $0.10/kWh, an S23 costs ~$340/month. With hosting at $0.07/kWh, that drops to ~$240/month, a significant difference over a miner's 3–5 year lifespan.

Most air-cooled ASICs run at 75–85 dB, comparable to a vacuum cleaner running continuously. Hydro-cooled miners like the Antminer S21 Hydro are significantly quieter at ~40–50 dB. If noise is a concern, consider hydro models or professional hosting where noise is handled for you.

Yes. MillionMiner specializes in B2B and bulk orders with volume pricing, dedicated account managers and custom logistics. Contact our B2B team with your requirements: model, quantity, delivery country and timeline. We also offer combined purchase + hosting packages for farm deployments.

The Bitmain Antminer KS7 (40 TH/s) is currently the most powerful Kaspa miner available. The IceRiver KS7 (30 TH/s) and Antminer KS5 Pro (21 TH/s) are also excellent choices. All use the KHeavyHash algorithm. Available at MillionMiner with free DDP shipping

The Bitmain Antminer L11 (20 GH/s) is the top Scrypt miner for Dogecoin and Litecoin merged mining. The Antminer L9 (17.6 GH/s), Elphapex DG1+ (14 GH/s) and VolcMiner D1 (17 GH/s) are strong alternatives. Scrypt miners mine both LTC and DOGE simultaneously.

A well-maintained ASIC typically lasts 3–5 years of continuous 24/7 operation. Economic lifespan depends on difficulty increases and newer models. With MillionMiner hosting, regular maintenance and climate-controlled environments extend operational life. Hosted miners also benefit from free on-site repairs by certified technicians.

MillionMiner accepts bank transfer (SEPA/SWIFT) and cryptocurrency (BTC, USDT, ETH and others). All payment details are shown at checkout. For bulk orders, we provide custom invoices with flexible payment terms. Always verify payment details match our official checkout. See our FAQ for security tips.

Yes, with efficient hardware and low electricity costs. The Antminer S23 at $0.07/kWh hosting can generate significant daily returns. Profitability depends on Bitcoin price, difficulty, and your miner's J/TH efficiency. Use WhatToMine calculators and always plan with multiple scenarios (best/base/worst case).

Hydro-cooled miners (also called water-cooled) replace fans with internal cold plates connected to a water cooling loop. Benefits: dramatically lower noise (~40–50 dB vs 80+ dB), higher hashrate per unit, better efficiency and longer hardware lifespan. The Antminer S21 Hydro (335 TH/s) and S23 Hydro (580 TH/s) are the leading hydro models available at MillionMiner.
