It should be, to make ICO comes back in the game, it must have some changes, especially in the way of listing the tokens or coins. People like to see a project that already lists their tokens/coins from the very beginning of fundraising. Many investors are traumatized that buying tokens from a new project but they are never listed on any exchange at the end. This is the fundamental reason that investors no longer trust ICO and turn to IEO. But if ICO does that way, how we differ ICO and IEO?
