I think many people afraid to invest in the ICO, FUD, SCAM and fail ICO everyday, I have the experience invested the fail ICO before, even the ICO is not successful finally, I still have not received my fund after 6 months, and the team is disappearing now.
With the 6 months frame without any signs that the ICO team is willing to pay those investors and participants then dont expect from them anymore. That is the worst thing if you put your money then there is no return anymore unlike when you only put an effort and only particpate it is not that kind of frustrating.
