There are many coins that have low value. and even those that should have no value exist. and also for coins that are on the crypto market but the volume is very low so that the coin is not interested depending on the news given by the developer coin. usually people see it from their announcement thread or on their website.
Oh yes, most low-turnover coins. Open at least a coinmarketcap and look at the coins from the 1000th number. There, everyone without exception has a daily volume close to 1k dollars or even less. And for the most part they are traded on very unpopular exchanges. The time of these coins is running out, I'm sure. And soon they will completely leave this market, giving prospects for new projects.
