Many new altcoins will die in the future because there won't be many investors investing money on them and as we know it we have many scammers here who will keep creating useless tokens and coins, if you are a developer and you think you are serious enough then try as hard as possible to come out with something new and different, enough of repetitive projects and same old ideas
Bring in something NEW or don't bother at all
I don't see anything really wrong in repeating ideals in a new project. Some good and worthy ideas have been abandoned probably because of financial challenges of developing such great idea further. So if another project with the aim continuing the development with some touched of improvement, then it's fine by me. What I don't like is plagiarism and repeating the same idea without any plan of improving it further from where the idea was picked up.
Honestly I can see clearly how dangerous repetitive projects can be, here are just few thoughts of my own
1. Repetitive projects fails easily because they aren't impressive to investors anymore, many investors have a bad story to share about projects with same use case
2. They get the job done faster for scammer, they can just copy all contents and give a different name to the project, this is why I don't like repetitive projects
