We never know what will happen in the future. LTC however primarily dropped out of the market in recent days. When we look back then we see that how LTC used to be top 3 ranked coin and had lot of volume everyday. But that trend went off the box in the recent month and whole crypto has started to look after other opportunities. Thus making LTC look like old master with no value in modern days now.
I do not think that litecoin is struggling at the moment. It is 6th on the coinmarket cap and it is not a bad position at all. Litecoin have already proven to the people what it can do and what it can bring. Investing in litecoin is a wise decision. Many people believe that litecoin can change the payment system with its lightning network. DOnt underestimate litecoin like that
Somehow I think that it is very struggling period for it as the competition has risen a lot these days. LTC is no where in that one.
