I want to write an article about this and I've been asking around.
So far, I've found:
* Fraud and scammers
* Government taking over
* Scalability and governance
How about you guys?
i will also talk about unrealistic and overpromising projects. The fact that anyone can generate an idea doesn't mean all should be channelled to crypto. So in the end very few people get interest in that and then it becomes a waste coin.
