If a crypto project gets too complicated to understand can it affect the projects adoption rate or people don't care this days where they put their money? I remember when Hex was launched many think it's a scam and so many complains about not understanding a thing about what the project is all about, what do you say ?
After all, Blockchain is a very complicated technology, and so many people have understood it. More and more people get to know about it and want to adopt it in business.
I think if a project is complicated, the developers just have to explain it. It is up to the developers to write a clear and easy to read whitepaper. This should guarantee success.
We are not talking about blockchain technology here, some projects have use cases that are confusing, I believe that's what OP is referring to, every blockchain newbie will surely find blockchain confusing at first but the discussion is about use cases that can't be understand, check HEx out for example
Giving an example with Blockchain is just an example that even a very complex project can be explained in some way.
As I wrote, the dev team is responsible for explaining the complexity of the project.
If the creators of the project cannot do it, the project in my eyes becomes suspicious.
This reaction seems perfectly normal to me.
