The fact that IEO is a form of mobilization is very smart because it minimizes risks for investors. However, there are two big problems that are common in IEO: the number of tokens that are being held too much by some people, if the token floor will bring a good amount to them, if the token is reduced to the floor then they will quickly take a loss or sell out of the market but the big risk is to be in new investors. Therefore, for those who have lost their money in this market, they lose faith and consider it a fraud.

IEO is not a scam, it is a new shape of ICO in cryptocurrency.
