If you hold the light coin at a higher price, you will definitely be able to recover it. The reason why the price of light coin is decreasing is to increase because if the price of token does not decrease then no one can buy and if not then no one can sell. So it is normal for the price of coins to fluctuate. You can definitely recover like coins from here.
So basicly, the reason why its decreasing is because people thing the coin is overvalued, and i believe it too. Since many another project are more interested to be invested than a old coin like LTC.
Move on, DeFi are cooler hype at the moment.
