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?
- 1st is lack of accountability by some (not all) ICO promoters. They just play with the investors money in ways that would get them to jail in any other situation.
- 2nd is cybersecurity. Everyday we wake up to know that an exchange or a service has been hacked.
- 3rd one is market manipulation. Pump and dumps and organised manipulation.
