I though the same thing, litecoin could go parabolic this bullish cycle. Last cycle litecoin and other PoW Old Coin is not perform very well, maybe because money flowing in to DeFi. But this time it will going back to " Non Securities " Coin which is LTC, BTC and Dash
Yes, hopefully it will happen this year because old coins haven't had good movements like other altcoins,
so this is why there is the potential to become parabolic for Litecoin because Litecoin will also do a halving,
we all know what the halving effect will be like.
Just continue to be patient man and soon you will be rewarded but as long as you are confident that the old coins you HODL are still stable in terms of developments. The other altcoins you mean might be the newly released coins. It's normal for them to pump at first because people always have the excitement for new things but don't worry because their shine can also fade later on and we don't know what can happen to them next.
Old coins are still better than them because we already know that their chance to recover is high. We already know what effect the halving can bring into Bitcoin and that is it can make its price rise but for Litecoin, it's said that its past halving performance are bad but maybe that will change this time, let's see.
