ICO / IEO is already finishing its journey, and IDO comes in to replace them on the DEX exchange. The first pedestrian was the TRXmarket with the TronAce project and the Binance DEX behind it with the Raven Protocol project. Both projects quickly raised funds and reached X. So the next step for IDO and the project Im waiting for Pledgecamp will be more interesting.
Raven Protocol token is first project doing IDO (Initial Decentralized Offering) in binance DEX. It was very successful and i think most project prefer their token sale managed by exchangers not by they own. Its good for investor because project can start listing in market without waiting too long
