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
What baffles me nowadays is the fact that most projects now see it as a normal thing to steal others ideas and even plagiarise their whitepaper and when caught they look for an excuse to cover it up and make it look like nothing. It's sad but this is the type of projects we have nowadays, only few upcoming projects are unique in their own ways others are always found wanting. Also, you have said it all but the question is, will there be a change, when it is now rampant? There might not be a change thus the reason to be weary of every project with such questionable nature, because for sure the team are only after the funds.
