it was slowly going up - then a "pump and dump" happened. I think it will go a little lower, and then continue growing like it did before.
Pump and dumps happen with many coins.
The good thing that comes out of it, is it attracts new users, and makes the community stronger, and the user base stronger.
I suggest you hold on to it, and let it grow - both the market, and your balance since Litecoin Plus does stake.
