Yes, now there are many bad projects and a lot of scam projects. But there are also promising successful projects.
The main factor that makes many scam projects is too many projects that are currently ICO live, if we are not careful then we can get a scam, the simplest thing that can be done to know an ICO scam or not is to know the team there.
There is a freedom to run an ICO so everyone who are willing can start an ICO even if they do not have the knowledge and the qualifications.
People should be careful, do not just invest directly, we should do our own research because blindly investing will most likely get your scammed.
