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%
Okex and Binance are favorite exchanges, lots of investors and traders are there, and of course there is huge capital.
so if IEO is held there then success will come to it
