Not really all of them, but I truly believe that a lot of scammers hiding to ICOs in order to accumulate money becuase it is the easiest way to fool the unaware people they don't what is really happening in ICOs right now. Of course, not all of them there's still a good ICOs with real people behind it and real project concept, like swachhcoin they have a lot partnership and has a real project concept and real people behind their project.
