Why do people think that in IEO is the solution to all problems? In fact, everything is not as good as it seems, so I think that in general, you just need to be prepared for the fact that now there are risks that cannot be avoided, you just need to try to control them.
IEO is indeed not the solution of all of them, but with IEO make things better ICO already very bad in the eyes of investor, besides it IEO is a project that has been filtered by a large exchanger, less likely to scam
