IEO or Initial Exchange Offering is a concept beyond ICO token sale (Initial Coin Offering). IEO is led by the registered cryptocurrency exchange. In this process, a token sale of a project will be hosted by exchanges such as Bittrex, KuCoin, Huobi, etc, on behalf of the project rather than the project itself. By doing so, the exchange ensures higher security level and prevents price manipulation. IEO is an advanced method of conducting the token sale and raising capital with the help of cryptocurrency exchange.
