Ethereum is very much more different than litecoin. Ethereum has a massive demand due to some ICO's making their coin on the ethereum blockchain that is why it hits the market. Also it appeals like money replacement like the bitcoin it has proven its use in the world of crypto.
Very much different why the moves is different between those both altcoins.
Litecoin popularity is behind etherium and the price too. So i am not surprising if you say litecoin is very slow.
