Well, that is actually one choice you may have to make on your own. Litecoin is not a bad hold, but the time you should have moved out have really passed.
However, I would really be looking for projects with unique products right now that just rounded up ICO and trading extremely lower than ICO price due to the market than sticking with LTC if you are looking for huge long term profit anyway. LTC is a good one, do not get me wrong, but as far as I am concerned, it is more like a coin in the shadow of bitcoin.
