LTC itself is not so much market movement. following the trend shaped by bitcoin and not much going on.
we can see LTC actually has a fairly high trading community.
We should also not question if it's dead or not because LTC still has a decent trading volume with over $3 billion on average daily based on the record in CMC.
I believe that the fact that Dogecoin is a meme coin, has offer it more visibility, perhaps even a more commited community, just because how exotic is almost everything around that project. Litecoin has a more serious approach than Dofecoin. I am just afraid investors can be so reckless that many of them would give up "seriousness" for the chance of more possible gains. Just my opinion,
