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%
Exactly, for a project to succeed they need a great exchange like binance as you mentioned, but remember that the team needs to source for fund to finance the IEO and exchange like binance have their fees on the High side which may be difficult for an average project to afford. It takes a whole lot to have ones token tradable on global exchange like binance which also means that the project would need to be up and doing to afford the cost of maintaining their tokens on the exchange.
