I have a moderate amount of LTC and the price has stalled quietly for a long time now. At some point LTC/USD will be easy to go higher when BTC flies above the current ATH. The real question is LTC/BTC will it have a major move up any time soon? If not, you are effectively losing some of your potential BTC stash as time goes by.
This is probably the reason why LTC stagnated in the last months. LTC (and other altcoin) hodlers saw that the Bitcoin price was going up significantly due to the ETF rumours since late 2023, and then after the final ETF introduction in the US in January 2024. Many have probably taken profits in the region around $100 and then invested them into BTC which looked healthier, and the LTC price dropped again.
Now what will happen in the future with the LTC/BTC market? That's of course quite difficult to predict, and I will also not try to shill anything.
In my opinion everything depends if the LTC/BTC market is generally in an equilibrium, where price swings do happen but are not significant -- this would mean that the current lower LTC/BTC price is caused by short-term speculation, like the profit taking/"riding the BTC wave" I mentioning above. This would mean that eventually the LTC/BTC market would be oversold, i.e. everybody who wanted to sell their LTC to buy BTC would have sold, which would allow demand to take over the market again and rise the LTC/BTC price.
Alternatively LTC could have a serious adoption problem, i.e. the growth of LTC users would be systematically slower than the growth of BTC users. This would justify a decrease of the LTC/BTC price.
I however am quite more fond of the "equilibrium" theory. The reason are simply the statistics I posted several times here. Litecoin is used more for transactions every year, it's the leading payment coin, its development is healthy, and there is an interesting synergy with Dogecoin which is merged mined and provides additional security.
Some stats which show that market cap is the only indicator where LTC really lags behind other major coins:
