Looking at the crypto space now, hype does not really say that the ICO is gonna be successful. ICO projects that have the potential of becoming successful are projects that have workable products which act as the backbone of the project. These products must solve a particular challenge seen in either the financial ecosystem or crypto ecosystem. With such projects, investors will be willing to invest in. The success of an ICO project is when investors invest in it massively.
Hype is almost guaranteed at every ICO now, but it's actually easy to see which hype is real and which isn't (which is paid, shilled, and which actually has real and authentic joy and amazement from the community).
But that said, neither of them seem to be any marker for a successful token. ICO raises aside, which hype has been met that I can recall? Monaco? Bittorrent? EOS? Nada.
