If btc shoots up before the new tech is up & working (segwit & lighting), like really shoots up (40-50k), ltc should follow all the way up to 500 and beyond.
If btc goes sideways for a long time and only explodes after it's been updated to handle the masses better then last time, ltc could prove to be less useful.
Let's not forget litepay, which could be huge if it gets adopted and used.
LTC is a good bet in my opinion.
Hope Litepay and other updates on LTC will set it apart from its "big brother".
