its never too late for litecoin halving to show better improvement
Litecoin Mining reward is no more 25LTC per block so even if value keeps shrinking its not bad,LTC is losing value because of present market condition,even BTC and ETH among the rest are taking the dives so if Altcoin Season returns now LTC will be among the most favoured since LTC halving already took place and mining reward is been cut into two.
Halving supposed to trigger the bullish trend on that coin but due to the market condition it is dumping after the halving as well but people recognize that this coin can give profits once bullish trend on bitcoin comes so surely people will be holding LTC or waiting to get more cheaper.
