nowadays we are witnessing the death of "raising funds with offering coins" which is known as ICOs but it seems like they keep trying to come up with different names for the same thing to try and keep it going a little longer. it was first STOs which failed and now it is IEOs which are even worst than anything they have done before because they are centralizing it to exchanges which are already shady and unsafe.
how much longer do you think this is going to last?
lets see after bitcoin crash again, ICO can last a very long time before bitcoin crashes I guess IEO will last a long time.
but the IEO in a large exchange will continue to exist, I think as long as there are still interested people they will continue to hold the IEO.
