I just found out if there was an ICO that was completed with the achievement of a very great fund, until 136 million dollars were reached.
seeing from the concept it doesn't seem scam only we don't see the project because of the many ico projects possible. I see they have also issued a mobile application
They are fraudsters and I recommend you read this article with all the details:
