If IEO is conducted on Binance, then the team and all project documentation will be carefully checked. Although Binance is very difficult to get to spend IEO. Recently I read statistics, only 4 of the 60 projects were selected and will be able to hold their IEO.
So it should be on the other exchanges. Only after careful selection of companies will the market once again be able to regain investor confidence. Last year, I had several times unsuccessfully invested in ICO and now have some fear.
