There are too many cryptocurrency projects and not all of them are really necessary for people. Bear market can show what projects are necessary for people and are useful and what projects do not have any practical volue at all.
If aren't really sure if a project is going to do well in the Future it's better you let go of it and focus on others or try to see if you will see others that you truly believe in.
Not all projects really have anything to offer to its investors if you look carefully you'll see that their main aim has always been just to rip off their investors nothing more.
