The success of ICO lies in the hand of huge partnership support, huge investors and trust but since scammers canes around ICO trust was ruined but now what we have left is IEO, and I will keep repeating myself over and over for new projects that the success of an IEO is top exchanges, no matter how good your use case is, if you choose p2pb2b or vindax over Okex or binance just have it at the back of your mind that failure awaits you with 80% chance over 100%
Because they have a large community, and as you said that the support that can be given okex and binance is much greater. Investors are an important driver for the start of a new coin, and if we see that some users of okex and binance have large capital which may play an important role as investors in an IEO project. Currently a good IEO project cannot run smoothly without the help of investors or a platform that can provide a path for the IEO.
