ASIC Miners for Sale — Hardware for Bitcoin, Dogecoin, Kaspa & Beyond

Bitcoin Miners

Bitcoin and Bitcoin Cash mining requires SHA-256 ASIC hardware. The MillionMiner catalog covers 227 current and previous-generation models from Bitmain (Antminer S21, S21 Pro, S21 XP, S23 series) and MicroBT (WhatsMiner M60, M66 series), available in air-cooled, hydro-cooled, and immersion configurations. SHA-256 miners work on both BTC and BCH networks, so operators can switch between coins through their mining pool whenever profitability shifts. Profitability in 2026 is driven by efficiency. Current generation hardware operates between 9.5 J/TH on the Antminer S23 Hydro 3U and 17.5 J/TH on the entry S21. At $0.08/kWh hosted electricity, a 13.5 J/TH miner runs roughly $210 per month. The same hashrate at 17.5 J/TH costs $270. That $60 monthly gap compounds to $720 a year, enough to shift a payback window by months. Every miner ships DDP. Buyers choosing hosting skip the home setup entirely. Hardware arrives at the US facility, gets installed, and starts hashing within days of order confirmation.

Dogecoin / Litecoin Miners

Dogecoin and Litecoin run on the same Scrypt algorithm, which means a single ASIC mines both coins simultaneously through merge mining. This dual-coin payout structure has made Scrypt one of the most consistently profitable algorithms outside Bitcoin throughout 2025 and into 2026. The category lists 60 current models from Bitmain (Antminer L7, L9, L11), VolcMiner (D1 Hydro), Goldshell, and ElphaPex. The ElphaPex DG Hydro 1 (20 GH/s) is a hydro-cooled Scrypt miner from a newer manufacturer that has built a strong reputation among hosting operators since launch. Bitmain's L11 series remains the highest-efficiency air-cooled option for home and small-facility deployments, while the L9 holds its place as the value pick for buyers prioritising payback speed over raw efficiency. Scrypt hardware has historically held resale value better than mid-tier SHA-256 because the manufacturing pipeline produces fewer units per generation. Buyers planning a 2 to 3 year hold often see stronger residual value at exit compared with comparable Bitcoin hardware. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Kaspa Miners

Kaspa mining uses the KHeavyHash algorithm, a BlockDAG-based proof-of-work design that produces blocks faster than Bitcoin while remaining ASIC-secured. The MillionMiner catalog covers 28 dedicated Kaspa miners including the Bitmain KS5, KS5 Pro, KS5L, IceRiver KS series, and Goldshell KA series. Kaspa is one of the newest minable proof-of-work coins to attract serious ASIC investment. Dedicated hardware launched in 2024, which means the network is still in its early growth phase compared to Bitcoin or Litecoin. Smaller market capitalisation creates the potential for higher percentage returns during favourable price movements, though revenue swings more sharply when prices move against you. Early adopters in emerging PoW coins have historically outperformed late entrants once network difficulty climbs. Hardware selection is more limited than Bitcoin because manufacturers are still scaling production. New models typically launch in batches with limited availability, so pre-ordering is common in this category and waiting lists move fast. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Ethereum Classic Miners

Ethereum Classic became the primary EtHash mining destination after Ethereum migrated to proof-of-stake in September 2022. ETC has continued to operate with steady network hashrate since the merge and remains the largest EtHash-compatible blockchain by market cap. The category covers 42 current models from Bitmain (Antminer E9, E11), iPollo (V1, V1 Mini), and Innosilicon (A11 Pro). EtHash hardware is not single-coin equipment. The same ASIC can mine ETC, ETHW (EthereumPoW), QKC (QuarkChain), and CLO (Callisto) by switching mining pools. This multi-coin flexibility protects buyers if any single chain loses profitability, because hardware can be redirected to whichever EtHash network offers the best return at any given time. ETC mining suits operators looking to diversify beyond Bitcoin and Scrypt without committing to brand new and untested algorithms. The ecosystem is mature, the hardware is well documented, and difficulty has been stable enough for accurate ROI projections. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Aleo Miners

Aleo runs the AleoBFT consensus mechanism, a proof-of-work design built around zero-knowledge proof computation rather than traditional hashing. The chain launched its mainnet in 2025 and is one of the youngest ASIC-mineable networks in production. The MillionMiner catalog covers 14 dedicated Aleo miners including the IceRiver AE1 Lite, AE2, AE3, and the Goldshell AE Max. Early ASIC adopters in new proof-of-work networks face less competition than miners entering after network difficulty has climbed. The IceRiver AE1 Lite (300 MH/s at 500W) is a compact entry point for home miners and small operators. The Goldshell AE Max (360 MH/s at 9.17 J/MH) is built for professional deployments where efficiency at scale matters more than upfront cost. Hardware selection is currently limited to 14 models because manufacturers are still ramping production. Specifications and pricing on Aleo equipment update more frequently than mature categories, so the catalog reflects the most recent confirmed availability from each supplier. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Alephium Miners

Alephium combines Bitcoin-style transaction security (the UTXO model) with smart contract capabilities, making it one of the few proof-of-work blockchains that supports programmable applications without abandoning the security properties miners rely on. The MillionMiner catalog covers 14 current Alephium models, led by the Bitmain AL3 series and variants. Mining uses the Blake3 algorithm. Blake3 ASICs deliver competitive efficiency in the 15 to 20 J/TH range, comparable to mid-tier SHA-256 hardware while operating on a far less saturated network. Lower competition at the network level means newer entrants face shorter waits for block rewards relative to invested hashrate. Alephium attracts buyers who want exposure to a smaller PoW chain with smart contract upside, without committing to highly experimental hardware. The Bitmain AL3 line is well documented, supplied through standard manufacturer channels, and supported by MillionMiner's hosting infrastructure. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Other Asic Miners

This category covers ASIC hardware for proof-of-work blockchains outside the main SHA-256, Scrypt, and Kaspa categories. The 89 models on offer span seven distinct algorithms: Blake2S (Kadena), Eaglesong (Nervos CKB), Blake2B and SHA3 hybrid (Handshake), Blake2B (Siacoin), Blake256 (Decred), Equihash (Zcash), and accelerators for RandomX (Monero CPU mining). Notable hardware in this category includes the Bitmain Antminer KA3 for Kadena, the Bitmain Antminer K7 for Nervos, the Goldshell HS Box for Handshake, and the Antminer Z15 Pro for Zcash. Some models support multiple algorithms within the same hardware family. For example, certain Blake-based ASICs can switch between Blake2B (Siacoin) and Blake2S (Kadena) to follow profitability shifts across networks. Buyers in this category typically have a specific coin in mind, whether for ideological reasons, geographic regulatory advantages, or simply because difficulty on smaller networks remains favourable for new entrants relative to Bitcoin or Litecoin. Every miner ships DDP and qualifies for hosting at MillionMiner's US facilities.

Hydro Miners

Hydro-cooled miners use closed-loop water cooling instead of fans to remove heat from ASIC chips. The result is lower noise (around 50 dB compared to 75+ dB on air-cooled equivalents), better energy efficiency, higher rack density, and longer hardware lifespan. Hydro-cooled facilities achieve PUE of approximately 1.03, meaning only 3% energy overhead beyond the miners themselves, compared to 20%+ on air-cooled data centers. Hydro miners are designed exclusively for data center and industrial hosting operations. They require 380 to 415V three-phase power, liquid cooling infrastructure, and 8 to 10 L/min coolant flow rates. They are not suitable for home mining and should not be ordered for residential deployment. The MillionMiner catalog covers 68 hydro models including the full Bitmain S23 Hydro lineup (580 TH/s at 9.5 J/TH, 865 TH/s, and 1,160 TH/s on the S23 Hydro 3U), the S21 XP Hyd (473 TH/s at 12 J/TH), and WhatsMiner Hydro variants. The majority mine Bitcoin (SHA-256), with select Scrypt and KHeavyHash hydro options for Dogecoin/Litecoin and Kaspa operations. MillionMiner's US hosting facilities support full hydro infrastructure including plumbing, flow monitoring, and pressure management. For operators building their own setups, Lianli radiators and cooling cabinets are available in the Equipment category.
