Gone are the days where you will make a lot mining unless you have 100+ machines. Until Bitmain comes out with a better miner, the L3+ is the best for mining scrypt coin. The difficulty keeps getting higher mining Litecoin. So, you will be lucky to make $2.00 /day if you mine it directly. You would be better off mining a different scrypt coin directly like Verge or Gamecredits. Or, sell your hashing power to nicehash and you will make $5 to $7 /day.
Either the value of Litecoin needs to increase or we get a faster miner to make mining Litecoin worth it.
