There are a lot of ICOs as well just with bad ideas run by not very competent people. Again with similar results for investors. It's hard to draw the line between them and scams.
I think ICOs being run by not very competent people is a big problem considering all the problems the company faces with an ICO based on what I read about companies have with successful ICOs.
Even if ICO companies are legitimate, they're stuck in a weird place between the law, taxes and other problems.
