Profitability Comparison
Antminer L3+
Antminer L7
Based on BTC price of $74,962 and current network difficulty as of Mar 17, 2026. Actual results vary.
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.
