If a coin introduces a completely new technology that enables a different function and is sustainable in the long term, does it have the potential to be a worthwhile investment?
If it is having a differentiating factor, it can be a good bet. Like, there are some privacy coins which are suited for different type oof audience. Same way , if there is some other coin which is targeting some other problem being faced by crypto users, it can be success. Other factors matter as well though. Like the team behind the coin. You should do a thorough research about the team behind the coin. Most of the scam coins have imaginary people in their team as their end goal is to run away with the money invested by investors in the coin.
The most important is to remember is that during the fall of the market it is possible to remember that not all the projects will be able to survive.
