LTC is always just going to be seen as a second best thing to bitcoin but it is worth very little without any merchants behind it or mainstream adoption.
Altcoins are from wild nature. You can't put your saving money to altcoins, it's too risky business. You don't want to waste your savings into some random cryptographic technology. They just copy each other, LTC is not unique.
I only trust Bitcoin in crypto-money world. So I would say yes. You should move your saving to Bitcoin.
