Anyone know how long usually it takes for ICO projects to list their tokens on an exchange? Is it different with other exchanges?
It depends on projects DEV team. Some coins will listed ASAP after ICO, some coins takes months... And some of them no time listing in anywhere.
I guess if the project is listed in an exchange too early, there is something not good in it. I prefer projects or ICOS that didn't rush to be listed but those having a value to their coin rather than letting others to sell it ASAP.
