It's very unexpected but that's the truth, most ico scam they just want to earn money for free, it's very difficult to choose which one is right, for example from the many bounty projects that you follow only a few are successful, it applies also to investors.
this is something we must accept because we cannot deny this reality. so for anyone if you want to invest in ICO, you have to be careful and be more careful in checking ICO to minimize errors in choosing ICO.
and it is true that what you are saying is that the number of failed ICOs is also comparable to a failed prize because I also found a lot of failed Gifts.
