I do not fully agree with you, because the even with the existence of Ieo can minimize fraud that occurs, but Ieo does not guarantee we will get a profit in the investments, we make, even though Ieo in the market is as large as the binance.
The last few months, I have noticed that Ieo in some markets is not It is different with ico, where when Ieo has finished, several token ieo projects continue to experience price drops quite drastic so investors / traders continue to suffer losses because the price of tokens has been far below the Ieo price.
so, I think Ieo does not guarantee we can get a profit.
Like you mentioned that it is in some market which I believe that there is no coin that has ever been listed on binance IEo that has never gotten increase immediately, and in fact, some records as high as 400x profit after their investment in the IEO, so for binance IEO, it is typically different from ICO that we know.
I agree with you that most of the IEO from other companies is as useless as ICO as all I see is just manipulation in the price after which they experience very massive dump which I have seen lots of people really complain about it, but for binance, this is a very sure project that has never failed someone's, and if you hear that they are releasing their IEO, just know that the investor should be expecting immediate profit in their investment.
