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?
I cant say this is unique way to investing in ICOs. Only a newbie in this world would still be wondering how to go about it. If a project is going to break barriers, it would be obvious from the start. These are basic knowledge everyone should have by default and if you don't, the market forces would be there to teach you so you learn the hard way and amateurs developer without any iota of praticability of their ideas are happy to collect your money without thinking twice at all.
