I think theres no more ico project and ieo projects are now invading the exchanges, but for me ieo and ico is almost the same, doenst mean if a project conducts ieo it will be successful, ive seen projects that made thier IEO but failed.
ICO and IEO are the same thing and the only thing that makes it different from one to each other caused by the exchange site that puts such ico to be launched on its platform and gets instant listing after that and so far there was a lot of failed IEO in the market that still exist until today. that's why to choose the old promising coin like credits is a better option.
