That is why the need for people, especially those investors of ICOs, to level up their investigation skills in terms of which is legit or scams is more necessary than ever. ICO investment is actually not for everyone, to be honest. It is not for those lazy ones who are not even trying to take a look and read the projects' whitepaper. It not the kind of investment for those who do not take time to carefully question the details of the projects.
You can say it like that but in reality in the current period of many developers, although the project is clear and detailed and no scam ignore the state of the coin in the market until the rate goes down and developers no development or improvement at all.
