Profitability Comparison
Bitcoin (SHA-256) profitability math does not apply here: both the Antminer L3+ and Antminer L7 mine Scrypt, not Bitcoin. Daily revenue depends on the target coin's network difficulty, block reward, and price, which move independently of Bitcoin difficulty.
Verdict
Two generations of Litecoin/Scrypt mining from Bitmain. The L3+ was the workhorse of an era, while the L7 represents a massive leap in Scrypt mining power.
The L7 is a generational leap that makes the L3+ obsolete for pure mining. The L3+ survives as a cheap used-market buy for Scrypt enthusiasts or space heater conversion.

Foire aux questions
Is the L3+ still profitable for Litecoin mining?
At current difficulty, the L3+ is barely profitable even with cheap electricity. It is most commonly repurposed as a space heater or kept as a collector item.
Can D-Central repair both L3+ and L7?
Yes. D-Central services the full Antminer L-series lineup with board-level repair capabilities.
