Asic L7

The Antminer L7 (released in late 2021) remains a well-known ASIC for mining Scrypt-based coins like Litecoin (LTC) and Dogecoin (DOGE), but its market position has shifted significantly in 2026 due to the arrival of more efficient successors.

Core Specifications & Tech Insights

The Antminer L7 operates with a hashrate of 9.05 – 9.5 GH/s and a power consumption of approximately 3,425W BitmainBixbit.

• Efficiency: Rated at 0.36 J/MH CryptominerbrosMiningnow.
• Algorithm: Specialized for Scrypt, optimized for merged mining (LTC + DOGE) Coincodex.
• Life Cycle: Now considered a "legacy" high-performance miner, as it has been surpassed by the Antminer L9 (16 GH/s @ 3,400W), which offers nearly double the hashrate for similar power draw D-CentralBt-Miners.

2026 Market Trends & Profitability

• Profitability Challenges: As of late 2026, the L7 is largely non-profitable at standard residential electricity rates ($0.10/kWh+), with daily net losses estimated around -$0.60 to -$2.20 MiningnowMiningnow.
• Threshold for Success: Profitability is only achievable with extremely low energy costs, typically below $0.05/kWh D-CentralCoincodex.
• Price Trend: Market prices for new units have plummeted from their original launch prices ($10,000+) to between $500 and $1,800 in 2026, depending on condition and vendor AlibabaAlibaba.
• Competitive Pressure: The launch of newer Scrypt miners like the Antminer L9 and efficiency leaders like the Fluminer L3 (0.179 J/MH) has accelerated the devaluation of the L7 AsicminervalueD-Central.

Sourcing Snapshot

Current B2B listings show a healthy supply of both new and used L7 units, as well as the high-demand L9 model.

• Antminer L7 (9.5 GH/s): Available from $499 – $567 (refurbished/base units) to ~$1,800 AlibabaAlibaba.
• Antminer L9 (16 GH/s): Pricing is volatile, ranging from $1,300 to $6,900 depending on stock availability and batch timing AlibabaAlibaba.
