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
naturally, there is nothing wrong with repititve projects or sorts. Because at the end of the day, it is left to hunters, marketers to decide if it is worth working for or not.
And if there is one thing I count important in this space, it is profit. People promote anything possible as long as it is legit and bringing profits, nobody wants to care if the project later dies or fumbles, as long as it brings rewards to their pocket.
