I couldnt agree on this. Some of the ICOs are not really scam but only failed to promote their project. Lack of promotion cannot make a project flourish.
I agree with you, there are lots of scam projects out there, but there are also projects who just fail to achieve their goals and fail to follow their plan according to some problems that occur on the way. But it's not fait to call them scam, because they try hard to succeed.
