They are worth it only in case you're sure that it won't die soon. Many projects grow fast and die with the same speed or even faster. New coins are good only in a short-term investment
that's true there required some analyzation before investing in these newer project since they have bigger chance of losing their value sooner than the already existing alts that's already famous like ETH and BNB.
most of the time, the newer coins are just gonna be losing their value as soon as their fame fading, as a result they become shitcoins.
