There should be more than 200 coins that will die in the future. Because most just make concepts without running them, nothing can really be applied to real life.
Maybe only a few percent of all altcoins can really be used, the rest is just speculation.
And another thing, the concept of one coin to another is almost certainly similar because yes they are trying to make a shortcut by copying an existing project.
Coins that have been dumped to the bottom and have a dead volume will not return, if they go up then they have to start the marketing concept again, or provide funds as an intermediary, IEO etc., or speculation only runs very short. The majority will become stone pebbles in the Desert and people are more happy with new quality coins and coins that are able to survive.
Projects that look copying, but there is always something that has more value. For example, we are talking about coins that focus on logistics, similar transaction systems, but applications, marketing areas, and supporting partners are different. Their ability to increase traffic and volume will also determine whether it will end successfully or not.
