Released in 2021, the Antminer L7 became the most economically durable Scrypt miner of its generation. Years later it’s still being run profitably — in the right conditions.
The specs at a glance
| Algorithm | Scrypt |
|---|---|
| Hashrate | ~9.5 GH/s |
| Power draw | ~3,425 W |
| Efficiency | ~0.35 J/MH |
| Coins | Litecoin + Dogecoin (merged) |
Does it still earn?
The L7’s economics now depend almost entirely on two things: your electricity cost and the second-hand price you pay. In low-power regions or on cheap hosting, it can still produce a respectable return on a modest upfront cost — one reason it remains popular on the used market in our miners marketplace.
The L7’s value proposition in 2026 is simple: lower entry price, higher energy cost. It works where power is cheap.
L7 vs. L9
The newer Antminer L9 roughly doubles hashrate and improves efficiency by ~40%. If your power is expensive, the L9’s efficiency usually justifies its higher price. If power is cheap and capital is tight, the L7 still earns. The trade-off mirrors the broader point in ASIC miners explained: efficiency buys you time as difficulty rises.
Verdict
The L7 is a budget-friendly entry into Scrypt and merged Litecoin/Dogecoin mining — best paired with very cheap power. If you’re optimising for the long term, weigh it against the L9, and consider running either through professional hosting.
Frequently asked questions
Is the Antminer L7 still profitable in 2026?
It can be, mainly in regions with very low electricity costs or on cheap hosting. Its higher energy use per hash makes power price the deciding factor.
Should I buy an L7 or an L9?
If power is expensive, the more efficient L9 usually wins long-term. If power is cheap and you want a lower upfront cost, the L7 remains viable.
What can the L7 mine?
Scrypt coins — Litecoin and Dogecoin together through merged mining, plus other Scrypt-based coins.
