Halving mostly forces price moving up. However, the price of Litecoin have increased dramatically since its bottom back in late of 2018 (in both trading pairs, LTC/ BTC and LTC/ USD). Consequently, I think that it is time for Litecoin to witness its corrections, especially when all altcoins have fallen down due to bitcoin bull run. This fact is hard to accept for someone whom bought Litecoin at high, especially in LTC/ BTC pair. However, the positive thing is altcoin season will start some day, and Litecoin will have chance to rally with upcoming altcoin season.
When is the halving happens? I think price should grow more, like this was with BTC before and after halving in 2016. After halving we had a huge bullrun. So, probably we will have the same with LTC in this year.
