Yes, actually during the boom of crypto projects dates back from 2015 to 2017, there were many ICOs that was successful, but unfortunately people saw this boom and the inflo of huge capital, which led many people into scam ICOs.
If you check back the memory of these ICOs, there were sincerelity amount new start up projects untill fraud came in because of Creed.
However, I think there are many projects that are very sincere to investor, traders and hunters may be because the era of ICOs is gradually fading away and has paved the way for IEOs.
