Yes I'm convinced that many altcoins will die osomeday. You might ask why and my answer is simple, because many projects have basically no use case at all while some are not even brought forward anymore due to a lack of developers or other reasons....
It's honestly just crazy to see that some of those projects are valued in the millions without even having delivered a single thing on their roadmap. It's nothing else than pure speculation by some people that keeps those tokens alive.
That being said I sometimes question the investment skills of some people within the cryptosphere. I mean why the hack would you put any money into thin air? Into something that doesn't even exist neither show any progress on github after all?
I personally am therefore only investing into products that show some progress and are actively engaging with the community about it. What's your approach on selecting the tokens you put your money on?
Yes I agree with you lots of Altcoins with no real purpose/ products and services will eventually die. but more new token/coin will born than die because of the trending ICO's happening elsewhere and because of the rising popularity of blockchain many company's has considered to used the phenomenal technology and released future token/coin too so its never ending competition because they are afraid being disrupted if they will not Innovate and use Blockchain.
