By the look of things, one may argue that this is true. Initial Coin Offering (ICOs) were doing very well in 2017 and early 2018 and many startups were able to collect billions of funds as capital to get their projects started. However, to date, no proper regulations have been put in place to monitor how the ICOs are carried out.
ICOs lack a third-party overseer. Therefore, scammers have found it to be a great opportunity to reap from the uninformed investors. As it stands, basically anyone can launch and run an ICO provided they are able to convince people that they have something they want to do and money is the hindrance.
Some governments like those of China and South Korea have banned ICO completely making it very hard for the genuine startups to fundraise through the ICOs.
The introduction of Initial Exchange Offering (IEO) was a game-changer. Startups even in those countries that had banned ICOs can now easily raise funds through crowdfunding since they shall not be breaking any laws.
In addition, though both ICOs and IEOs share some degree of rationales, in IEO, there is an overseer who is normally the exchange platform through which the IEO is being run.
For a development team to run any IEO, they have to meet and comply with the requirements set by the exchange. Therefore, the exchange acts as a cushion for investors. Investors are guaranteed that whatever the exchange is offering is well cross-examined and that it is not a scam. As a matter of fact, if the IEO was to be a scam, it would ruin the reputation of the exchange which still needs to continue with its activities after the IEO.
