In fact, ICOs project in 2017 or last year are can become to scam project, but the time they become to scammer still long. Because if try scam at now, they will miss opportunity make money with this type. Not have rules can helps them easy to PR and creating project, just need use some money from crowdsale, they can easy listing to exchange site and user will say they are really project

You mean that they would rather finish an ico, issue tokens, get listed on the exchange and only then scam than disappearing right after money is raised?
