Another thing that is keeping Litecoin alive is the fact that we are seeing it go on longer than people expected it to go on and that gives it a boost. Normally if it was invented just last year then it would have been gone already, but we all know that it has been around for over a decade already and that means it is not a bad one and it could be trusted for being here so long. Not even about itself, not about litecoin, not because it is great or anything, but only because it has been around for longer than any other aside from bitcoin. That time alone itself is a huge boost to its price and how much people trust it.
There is definitely some truth in what you say, but the age of a coin is not enough to constantly attract new investors and more and more money to their project. Because we know a lot of examples of old coins, which are on the market for a long time, but nobody needs them and nobody buys them. But LTC has big community among investors and miners, that's why with each new bull run it grows in value more, than in previous cycle, and not every coin, even those that are on the market for a long time, can do that.
