For now, IEO, which is quite good, is IEO which was released by binance because it has a large enough audience. this has been proven by the many people who are so interested in binance. they almost all followed this investment
No, I do not agree with your point all Ieo is not conducted by binance or not listed only on binance, Sistemkoin, W12.io etc are also a good exchange and many good projects are listed on it. like Moozicore
