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 think this is strongly the major cause for which people have little or no investors committing their investments into projects. Unlike the days of Scalability and security on the blockchain, where alternative blockchains had to stand in the gap, today we have loads of projects that are solving no real use case as a challenge. let there be new innovations that will attract investors and solve a real life problem.
