Honestly, this is the best trend right now compared to that STO. Investors will be confident that their money is on the right place because a reputable exchange like Binance will surely strictly review these projects before advertising it on their platform. It's the best way to get rid of scam ICOs and bring back the trust of new investors or past investors again in this industry.
It will only get rid of ICO scams provided most project migrate to IEO and I do hope their policies for IEO is not too strict to force the project into staying with ICO, if they can succeed in making virtually every crowdfunding projects migrate to IEO, then we can be rest assured that they will regain the trust of potential investors out there and aside the scam issue too, is to also be sure that whatever project they are listing is very viable and will definitely continue to grow in the long run and not eventually turn to shitcoins they will end up delisting themselves.
STO and IEO may bring back confident into crypto space among investors which will definitely lead to win-win situation for all of them.
This is the expectation of this community but how far this new trend will go by keeping their word will be a time determinant. I remember ICO industry was highly successful when crypto market was trading positive but in downfall, due to lack of investors, most ICOs ended up failing due to improper managements.
