IEOs certainly seem to have advantages over ICOs most notably being "ease" of having everything take place on one exchange but many scam exchanges such as coinsbit and p2pb2b are sending fake volume to Coinmarketcap to try to make themselves looks bigger and better than others but in the end they are nothing more than modern day thieves waiting to scam as many users as possible before exiting. They are even operating their own IEOs using their own fake IEO projects in the hope to dupe users.
Which IEOs would you say were successful in 2018/19?
