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
New idea is better and futuristic but this doesn't mean that the new project will do better in the market, I've seen many examples already, sometimes the community love for an old project is stronger than what the new project will ever have
