litecoin price does not increase much in short time but it never moves from its top position its market cap is always very high so I don't think anyone should worry about litecoin. Litecoin can be a safe investment even though it may not be able to give much profit in short period of time but it will not expose anyone to excessive losses in short period of time like other coins.
That type of understanding the crypto world and litecoins value in it is the reason why some people earn money maybe a little less at times but keep on earning whereas others may end up earning more for a short period of time but end up losing it.
Like for example let's compare SOL vs LTC, it is true that SOL has done a lot better for the early investors, if you take it from early days of SOL and compare them then it made people a lot more profit, but I bet that in 10 years we won't even remember SOL let alone being in the top 20, whereas I believe that Litecoin would still be around by then. This is why I invested into tested and known veteran projects over newer ones.
