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 saw a lot of new projects but did not show its development even the price was far below from the initial price. possibly most of them get launch due to want investor funds. there are some Defi project for example Oikos, Jarvis, dia data who has made enough hyip in crypto market
Because they create new projects to make money, they just copy it from the old projects and then list it in the exchanges. They would then sell it all and cause the price to crash hundreds of times. There are very few quality projects, and the projects you list are the best at the moment.
