Litecoin will hit $15 or $20 just before the halving. that is my prediction. and i am no newbie. I've seen a lot of crazy things like Aurora Coin pumped to $100 in 2 -3 days. So $15 - $20 for Litecoin is absolutely doable.
To keep LTC between $15-20 buyers should keep pouring 400-600K USD into LTC every day, just for maintaining the price. After the halving such a pump would be much cheaper, so the profit would be much higher.
