Interesting thoughts. Anyway, for Litecoin the same is valid as for Bitcoin: It's dominated by huge farms with mostly low-priced (maybe even free) energy. Until you want to mine 0.00x LTC per day with low hashrate devices, it might probably be better to mine other altcoins and either sell them immediately (for BTC, buying LTC with them) or keep them and sell at better prices. Even if, due to certain factors, the price won't increase in general for some time, there are still pumpers who will play the pump & dump game.
