no, but if people really believe in decentralization it might happen. but in reality decentralization only provides bigger opportunities for scammers. so those with doubts will still choose IEOs to invest in new projects. and IEOs on major exchanges also still have a big impact on increasing the popularity of the project.

so IDO will probably only be an option for Defi projects and the like. projects that are less concerned with government regulation will use IDOs, and the remainder will continue to use IEOs as a means of raising initial funding.
