I don't know that Litecoin mining is still going as before, due to the way we have been hearing silence about the coins, though I don't know much about it's mining, but from the way things have not been so trending in discussing about Litecoin signifies a little drop from the coin in terms of it's mining capacity, but of no doubt, Litecoin is one of the most valuable coins I've ever trusted till today.
Definitely there will be people still mining Litecoin and that is why we still have it transactions confirmation and at the same time the chain being running and having one of the lowest and fastest transactions confirmation it shows how active the miners are, although we may say Litecoin mining may not be as popular as before may the block reward is not as high as before.
