Yes, but litecoin is good be traded on poloniex because the trend of litecoin is increasing
it is good time for make profit from trading altcoins, although maybe today is time for going down of litecoin,
what I know why litecoin is increasing because of the activation of segwit in litecoin,
although it is not 100% true but it is good news for litecoin.
Litecoin, although it lacks development and innovation, makes it a great cryptocurrency for trading due to its relatively stable price movement on the markets. Especially nowadays, as it has seen a price uptrend due to investor interest into it, because of SegWit's acceptance from the miners.
While the activation of the scalable solution for Litecoin is uncertain (as now it has gone below 75% of the hashrate supporting it) it is fun to watch its price rise, for those who have invested into LTC earlier.
I think that it will be quite interesting to see how SegWit would turn out to be in Litecoin if active, as it will serve as a testing ground for Bitcoin. Nevertheless, I hope that someday, Litecoin could deliver innovation and true development to help it become the second crypto in market cap, like it used to be. Just my opinion.
