I don't think so. So many people are very enthusiastic about joining IEO. Because they can get a lot of benefits in an instant. Therefore, IEO may replace ICO in the future.
I do not understand what you said at the beginning of your sentence saying that you do not agree that IEO will be good in the future, but why in the next sentence you agree with it. even saying that IEO will replace ICO in the future.
