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 ?
In my opinion, the problem is not how complex a project is to be successful, but how informed and educated the society is. In general, if someone has decided to invest all their money, they should be more interested and research the projects, and even if something is not clear by reading and asking it could be understood.
It is not possible for all projects to be very simple to be understood by everyone at once, every new thing is learned over time and gets used to it.
