It doesn't mean that when a certain coin is not being talked about, it's dead already but it's more like not relevant to the current trend or narrative that we have on the market. It's always about the narrative when it comes to being talked about.
You would consider it dead if there's no volume and no one is trading it anymore. It's not the case with LTC.
Yes that's right, it doesn't mean that a project is not talked about so they are claimed to be dead, if we use the network on Litecoin it can still be used, indicating that it is still alive, but indeed when no one is talking about it is normal because it doesn't have many project developments that match the discussion of the progress of the narrative in the cryptocurrency industry, it's just that in my opinion Litecoin lacks popularity because there are few demographics or adoption in terms of use casa the crypto hunters are not really looking at it.
This is the same as market performance in general, we see a definite trend that people will prefer to the field that has a trend at this time for their use.
