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 ?
The main reason why people invest is to gain profit. No matter how easy or hard a particular coin can be, people will always look for its market status and how profitable it could be unless a coin faces many issues that could make lots of investors doubt its potential. Most people these days just follow the trend, and they choose to invest with coins with good volume.
