Well, that is the sad reality of ICO projects of this era. Only few are worth the time and effort. IEO is the one on trend right now and according to a lot of people, it is less risky. You should try that one.
Right, I also really believe in IEO that is trending right now, because there are so many projects that use sales through IEO successfully, so it doesn't hurt if we all try to join projects that use IEO for token sales.
It will not hurt you until you experience to lose from it. We all know that IEO is the new trend but it doesn't mean every trend you need to follow. You should be aware about the risk the result for long term is the same as in any other project with ICO,STO,IEO they are all just want investment.
