It really is hard to believe that there are some ICOs who are intended to scam people. There are all hypocrits and rely on the weakness of people especially those who are new to bitcoin. So sad.
There aren't just some or few ICOs that try to scam people, there are lots of ICOs out there trying to scam. Some of them being complete scam and you can see it right away, and some of them well thought and even ranked high on few ICO review, but after ICO and TGE they turn out to be complete scam not even trying to achieve roadmap goals. I invested in few of those that are completely off their roadmap (doing something else) or that aren't even trying to keep up with their goals, and where is ICO money going nobody knows... That's the proble of this still unregulated space that basically people can do whatever they want with no sanctions at all yet.. So still be very cautious out there, and even if everything feels alright, here in crypto world it can easily turn out to be scam.
