IEO (initial exchange offering) is a effective method whereby an ICO or regulated ICO (STO) is held for public sale on a centralized or decentralized exchange. IEO‘s initially began in mid-2014, when Syscoin hosted one of the first IEO‘s on an exchange known as Moolah (a subsidiary to former exchange giant Mintpal), which was clouded by fiascos and scandals. IEO‘s benefit greatly from established exchanges reputations, security and authority of the crypto-currency markets by catering directly to their active traders, investors and new audiences who may be attracted by the offering. In addition, most centralized exchanges have existing community outreach and marketing tactics available, helping promote the IEO further for expedited sales and diminishing risks of listings after an ICO or STO is conducted in-house. There are several distinct advantages for upcoming teams to efficiently utilize the IEO method, but projects have to typically undergo rigorous examinations, have an already proven project (or testnet/MVP) and more often, pre-funded with already existing large communities.
