i disagree, in fact i say IEOs are even less safe than ICOs because exchanges are involved. they don't care about legitimacy of the projects they advertise, they may only do it at first but eventually they will end up promoting only those that pay them the most. and before you know it you will start seeing only big scams being promoted in these exchanges that can cause so much damage to the whole market.
Although I do not like IEO, I still have to recognize IEO as safer than ICO in terms of fraud and poor quality. Of course, here I only mention IEO of reputable large exchange platforms like Binance. But why do I think IEO will be difficult to maintain for a long time and it has disadvantages compared to ICO:
1. Lost the decentralized nature like ICOICO is created to allow everyone from small to large investors to participate, everyone can contribute, as long as you are valid with the rules set out. But the IEO is different, in order to be able to buy token from the IEO, you must follow a lot of principles from them and not everyone can buy it.
Example: According to the latest rules from Binance, to be able to join their IEO you must have BNB in the account, limit 20 days to the lottery draw date. The more BNB balances, the greater the opportunity to buy IEO tokens.
This suggests that everyone who wants to participate in Binance's IEO will be dependent on BNB. And the rule above, it seems that their IEO is only for big investors.
2. Inflation and dependenceWhat do you think when everyone wants to join Binance's IEO? They are forced to buy BNB and make its price inflated. Since then, the most benefited people from IEO are not investors but Binance, they have succeeded in pushing BNB prices. But IEO is like ICO, it does not guarantee 100% profit, it still causes losses like ICO, of course that Binance will not be responsible. From that point of view, the IEO is a game where the exchange platforms will be the most benefited people, investors will still suffer certain risks.
So I think the IEO will not be sustained for long or the IEO will have to improve more so as not to be too dependent on the exchange platform.
