Litecoin had a pretty bullish year in 2017, so I don't think that we'll see price hikes like last year again.

I don't see any all time highs coming for LTC this year, considering that the crypto markets are still correcting downwards on a daily basis. It would be extremely hard for LTC to go against the overall crypto trend.

We could see pumps here and there, but that's about it. There will most likely be no sustained bull run.
