I don't think there will be much to be expected because usually, when a blockchain is expected to undergo halving, two weeks before that day is usually dump from traders as they want to have their profits before that day, the wise ones don't want to be trapped in the circle of whales games, so I don't think there is much to be expected from to that day.

In addition, over the years, altcoin halvings don't generate much attention like Bitcoin where you will see lot of request in google search engine, demand for Bitcoin usually exceed all time during Bitcoin halving and after that period, bullrun use to commence.
Agree. Litecoin's price in particular seems not really to react much to halvings. In the prior halvings, 2015 and 2019, the market around halvings - if we consider LTC/BTC - was even bearish, with major pumps having occurred at times totally unrelated to the halving date (halvings marked in red):
Source: Yahoo FinanceThis is not the case this time, when LTC is more or less in a sideways market, slightly bullish with respect to 2022. The brief $115 peak could be related to halving speculation, but this is not totally clear to me, it could also having been caused by euphoria because a jump in the general altcoin market was expected at the time around Bitcoin's 31800 high. As long as Bitcoin stays within its current range (let's say 27000 to 32000), I currently don't expect too much variation in the LTC price.
About post-halving expectations:
LTC has currently a trading volume of ~500 million-1 billion USD per 24 hs. Miners generate only 660000 USD worth of LTC per day (1 LTC=92 USD, 24 blocks/hour, 12,5 LTC/block). Even if they sell all of them instantly, it's only 0,06% to 0,12% of the total trading volume. So they have next to no power on the selling side. After the halving, miners' importance will go to 0.03 to 0.06 %. I don't think that makes much of a difference. But it shows that LTC supply already isn't getting diluted much by miners. Even less than in the case of BTC, where they have 0,1-0,15% (25 million/day, 20 billion volume). Thus we could say that LTC is currently even more "scarce" than Bitcoin, if we only look at the supply side.
